The Honda Civic Si sits in a sweet spot between daily commuter and genuine sport compact, and finding the best Honda Civic Si accessories takes that experience even further. Whether you drive a 10th gen model from 2017 to 2021 or an 11th gen from 2022 onward, the right add-ons protect your investment, sharpen the driving feel, and make the cabin a better place to spend time.
Our team spent weeks researching forums, owner reviews, and real-world install stories to put together this guide. We focused on accessories that deliver real value rather than just looking good in a listing photo. That means everything from all-weather floor mats to a cold air intake that actually wakes up the 1.5L turbo.
One thing we noticed across Reddit threads on r/CivicSi and the Civic 11 Forum is that new Si owners constantly struggle with generation compatibility. Parts for a 2019 Si will not fit a 2024 Si, and vice versa. We called out fitment details for every product in this guide so you do not waste money on the wrong part. If you are looking for performance-specific upgrades, our guide to the best cold air intakes for Honda Civic Si dives deeper into intake options.
Top 3 Picks for Best Honda Civic Si Accessories (July 2026)
Out of every product we reviewed, three stand out for different types of owners. The LASFIT Floor Mats protect your interior from day one. The K&N Cold Air Intake unlocks performance from the 1.5L turbo. And the TANDRIVE Key Fob Cover is an affordable essential that keeps your remote looking new.

1. LASFIT Floor Mats – Best Overall Interior Protection
LASFIT Floor Mats for Honda Civic 2022-2025 2026 Sedan Hatchback Si (Include Sport), with&w/o USB Port | for Acura Integra 2023-2026, All Weather Car Floor Liners, 1st & 2nd Row, Black
Fits 2022-2026 Civic Si
3D laser scanned TPE
All-weather raised edges
1st and 2nd row
Pros
- Perfect custom fit using 3D laser scanning
- Premium TPE material more pliable than WeatherTech
- Excellent coverage beyond factory mats
- Easy to remove and clean
- Great value vs dealer options
Cons
- Dirt can set into textured surface over time
- Not compatible with Hybrid models
When I first installed the LASFIT floor mats in a Civic Si, the fit immediately stood out. These mats use 3D laser scanning technology to match every contour of the 11th gen Civic footwell. There are no awkward gaps where dirt and water can sneak past onto your carpet.
The TPE material feels flexible yet substantial. Unlike cheaper rubber mats that curl at the edges, these stay flat and hold their shape. The raised lip around the perimeter catches everything from muddy shoes to spilled coffee without letting it reach the carpet underneath.
Cleaning is simple. I pull them out, hit them with a hose, and let them dry. The textured surface does tend to hold onto fine dirt if you let it build up too long, so a weekly shake-out keeps them looking fresh. Several owners on the Civic 11 Forum mentioned these mats specifically as one of their first and most recommended purchases.
At this price point, the value compared to dealer options or WeatherTech is hard to beat. You get first and second row coverage for the full cabin. Just confirm you do not have the Hybrid model, as LASFIT lists those under a separate product.
What Years and Trims Does It Fit?
The LASFIT mats fit the 2022 through 2026 Honda Civic Sedan and Hatchback Si, including the Sport trim. They also work with the Acura Integra from 2023 to 2026. Check whether your center console has a USB port or not before ordering, as LASFIT offers variants for both configurations.
How Does It Compare to WeatherTech?
Multiple reviewers noted that the LASFIT TPE material is actually more pliable and easier to work with than WeatherTech. The fit is just as precise thanks to the 3D scanning process. The main difference comes down to price, where LASFIT consistently undercuts the competition while delivering the same all-weather protection.
2. K&N Cold Air Intake System – Best Performance Upgrade
K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Acceleration: Compatible with 2017-2020 Honda: Civic SI, 69-1504TR
Fits 2017-2020 Civic Si
Guaranteed HP gain
Washable cotton filter
Lifetime warranty
Pros
- Guaranteed horsepower and torque increase
- Improved throttle response
- Aggressive engine growl on acceleration
- Washable filter lasts 100k miles
- Lifetime million-mile warranty
Cons
- Premium price point
- Currently faces stock availability issues
- Gains may be modest on stock vehicles
The K&N cold air intake is the performance accessory that 10th gen Civic Si owners talk about most. K&N guarantees a horsepower and torque increase, and they include dyno test reports to back it up. When I drove a Civic Si with this intake installed, the difference in throttle response was immediately noticeable.
Beyond raw power, the sound transformation is what sells most owners. The 1.5L turbo gets a deeper, more aggressive intake growl under acceleration. It makes the car feel more alive without being obnoxious during normal cruising. For a deeper dive into intake options, check our full guide on cold air intakes for the Honda Civic 1.5L turbo.
The washable cotton filter is a major long-term value point. Under normal highway driving, you only need to clean it every 100,000 miles. The filter uses four layers of pleated cotton with K&N red filter oil to trap dirt while flowing more air than a disposable paper filter.
Installation takes about an hour with basic hand tools. K&N includes all necessary hardware and detailed instructions. The system is designed to not void your manufacturer warranty, which addresses one of the biggest concerns new Si owners have about engine modifications.
How Much Horsepower Does It Actually Add?
K&N dyno tests the intake specifically on the Civic Si and includes the report in the box. Real-world owner feedback suggests you feel the improvement most in mid-range throttle response and during highway passing. On a completely stock vehicle, the gains are real but not dramatic. The intake shines brightest when paired with other bolt-ons like an exhaust system.
Will It Void My Warranty?
K&N designs this intake to work within factory parameters and states it does not void the manufacturer vehicle warranty. However, if you have concerns, check with your dealer before installing. The Magnuson-Moss Warranty Act protects consumers, but having the conversation upfront saves headaches later.
3. EcoNour Windshield Sunshade – Best Value Protection
EcoNour Windshield Sunshade Compatible for Honda Civic 11th Gen 2022-2024 2025 2026 Including LX, Sport, EX, Touring, and Si Window Sun Shade Cover, UV Heat Blocker & Protector, Car Accessories
Fits 2022-2026 Civic
4-layer UV block
SPF 100 UPF 80+
280T polyester
Pros
- Excellent vehicle-specific fit
- Blocks 99 percent of UVA and UVB
- Easy to install and fold
- Comes with storage bag
- Thin yet durable material
Cons
- Storage bag can be tight fit
- Spring steel edge may weaken over time
- Velcro strap fit varies
The EcoNour windshield sunshade is the number one bestseller in automotive sunshades, and for good reason. It is custom-cut for the 11th gen Honda Civic windshield, which means full coverage without the gaps you get from universal sunshades. I was surprised how well it fills the entire glass area on the Civic Si.
The four-layer construction blocks 99.89 percent of UVA and 99.95 percent of UVB rays. With SPF 100 and UPF 80+ ratings, this shade seriously reduces cabin temperatures and protects your dashboard from sun damage. On hot summer days, the difference in interior temperature when you return to the car is significant.
The 280T high-density polyester material feels thin but effective. Reinforced stitched edges prevent the warping and bending that plague cheaper shades. It folds up neatly and comes with a storage bag, though getting it back into the bag takes a bit of practice.
One thing to watch is the spring steel edge. Over time and with frequent folding, it can lose tension. Several long-term users mentioned this, but most found the shade lasts well over a year of daily use before any issues appear.
How Easy Is Daily Installation?
Installing the EcoNour shade takes about 10 seconds. You unfold it, tuck it behind the rearview mirror, and secure the Velcro strap around the mirror post. Removal is just as fast. The whole thing folds into a compact bundle that stores behind the passenger seat or in the trunk.
Does It Work With a Dash Cam?
Yes. Multiple reviewers confirmed the shade works fine with a dash cam mounted behind the rearview mirror. You just route the Velcro strap around the mirror and dash cam cable. The shade material is thin enough that it does not interfere with the mirror adjustment.
4. Coleya Anti-Glare Screen Protector – Best Display Protection
Coleya Anti-Glare Matte 2022-2026 Civic Screen Protector, for Honda Civic (Si/Type R/Sport Touring Hybrid/Touring) 9-inch Touchscreen, 9H Tempered Glass 2025 Civic Accessories HD&Anti-Fingerprint 9"
9H tempered glass
Anti-glare matte
Fits 9-inch Civic screen
0.28mm thin
Pros
- 9H hardness protects against scratches
- Anti-glare matte reduces sunlight reflection
- Anti-fingerprint coating keeps screen clean
- 98 percent optical clarity
- Bubble-free installation
Cons
- Matte finish slightly reduces clarity for some
- Only fits 9-inch screen not 7-inch
- May need replacement if heavily scratched
The 9-inch touchscreen on the 11th gen Civic Si is great, but it is also a magnet for fingerprints and glare. The Coleya screen protector solves both problems with a 9H tempered glass layer and a matte anti-glare finish. I installed one and immediately noticed how much easier the screen is to read in direct sunlight.
The 0.28mm thickness keeps touch sensitivity intact. Every tap, swipe, and pinch works exactly as it did before installation. The 98 percent optical transmittance means the display stays bright and colorful despite the protective layer.
The matte finish is the real selling point for the Civic Si. The factory screen is glossy, which means it acts like a mirror when sunlight hits it at certain angles. The Coleya protector diffuses that glare so you can actually see your navigation and music info without squinting.
Installation was bubble-free in my experience. The kit includes everything you need to align and apply the glass. Take your time cleaning the screen first, because any dust particle will create a visible bump under the glass.
Which Civic Models Have the 9-Inch Screen?
The 9-inch touchscreen comes on the Civic Si, Type R, Sport Touring Hybrid, and Touring trims from 2022 onward. If you have the base 7-inch screen on an LX or standard Sport trim, this protector will not fit. Coleya lists compatibility clearly, so double-check your screen size before ordering.
Does the Matte Finish Hurt Screen Sharpness?
There is a slight reduction in sharpness compared to the bare glossy screen. Most owners consider this a fair trade for the glare reduction. If absolute clarity is your priority, a glossy protector might suit you better. But for daily driving where sunlight is a constant issue, the matte finish wins.
5. pop-tech Magnetic Phone Holder – Best Interior Convenience
pop-tech Magnetic Phone Holder for Honda Civic 11th Gen 2022 2023 2024 2025 2026, 360° Car Screen Phone Mount Made for Civic Hatchback Sedan Touchscreen, Compatible with Magsafe iPhone Accessories
Fits Civic 11th gen
MagSafe compatible
360 degree rotation
Adhesive mount
Pros
- Perfect custom fit for Civic touchscreen
- 360 degree rotation for any angle
- Strong magnetic hold on bumpy roads
- Easy one-handed operation
- Clean aesthetic blends with interior
Cons
- Adhesive may weaken in hot climates
- No wireless charging included
- May not fit cases with grip handles
The pop-tech magnetic phone holder is designed specifically for the Honda Civic 11th gen touchscreen. It mounts directly to the screen bezel using adhesive, which means no cluttering your dashboard with vent clips or suction cups. The integration looks almost factory-installed.
The MagSafe compatibility is what makes this mount shine for iPhone 12 through 16 series owners. The magnet holds firmly even on rough pavement. For Android users, the kit includes metal ring stickers that attach to the back of your phone or case to enable magnetic mounting.
The 360-degree ball joint lets you switch between portrait for GPS navigation and landscape for music control. The adjustment is smooth and stays put once you set your preferred angle. I found one-handed mounting and removal effortless after the first day of use.
The one concern is adhesive longevity in hot climates. Several reviewers in southern states mentioned the mount needed re-adhesion after a few months of summer heat. pop-tech includes a replacement adhesive strip in the box, which addresses this proactively.
Will It Block Any of the Touchscreen?
The mount attaches to the top edge of the screen bezel, not the display area itself. Your 9-inch touchscreen remains fully visible and accessible. The phone sits above the screen when mounted, which actually puts it at a natural eye level for navigation.
Does It Work With Thick Phone Cases?
MagSafe iPhones work through most standard cases. Very thick cases or cases with built-in grips and stands may interfere with the magnetic connection. If you use an Android phone, the metal ring needs direct contact with the magnet, so it works best on a flat case surface.
6. Femibon Rear Spoiler Wing – Best Exterior Styling
Femibon Rear Spoiler Wing Compatible with 2022 2023 2024 2025 2026 Honda Civic Sedan Sport Rear Trunk Spoiler Wing Lip for Honda Civic Sedan Accessories (Glossy Black)
Fits 2022-2026 Civic Sedan
Glossy black ABS
Self-adhesive install
2 year warranty
Pros
- Perfect fit for 11th gen Civic Sedan
- Durable reinforced ABS plastic
- Glossy black finish matches vehicle
- Self-adhesive installation
- 2 year warranty included
Cons
- No printed installation manual included
- Adhesive weakens below 10 degrees C
- Requires 24 hours before water exposure
The Femibon rear spoiler wing gives the 11th gen Civic Sedan a noticeably more aggressive stance without the cost of a painted OEM spoiler. The glossy black ABS finish pairs well with the Sport and Si trims that already feature black accents. I was impressed by how OEM-like it looks once installed.
Installation uses thermal double-sided adhesive tape. No drilling is required, which is great for lease vehicles or anyone who does not want to put holes in their trunk lid. The key is prepping the surface properly and allowing the adhesive to cure for 24 hours before any water exposure.
The ABS plastic construction feels solid and has held up well for owners through car washes and highway driving. The reinforced structure prevents the wing from flexing or vibrating at speed. Femibon backs it with a 2-year warranty, which adds confidence to the purchase.
One thing to note is that no printed installation manual comes in the box. Femibon provides a video guide instead. I recommend watching it before starting, and if you are installing in cold weather below 10 degrees Celsius, use a hair dryer to warm the adhesive for a proper bond.
Does It Fit the Hatchback Model?
This specific spoiler is designed for the Civic Sedan only, fitting model years 2022 through 2026. The Hatchback has a different trunk profile. If you own a Hatchback Si, look for a spoiler specifically listed for the FL1 or FL5 chassis codes to ensure proper fitment.
How Long Does Installation Take?
Plan for about 30 to 45 minutes including surface prep. The actual adhesive application takes only a few minutes, but you need time to clean the trunk surface thoroughly, align the spoiler carefully, and apply consistent pressure. Then wait 24 hours before driving in rain or taking it through a car wash.
7. CKE Sport Mirror Covers – Best Budget Exterior Mod
CKE 2pcs Compatible with Honda Civic 2026 2025 2024 2023 2022 Accessories Aggressive Look Sport Door Side Mirror Cover Exterior Rearview Mirror Guard Cover Trims -Glossy Black
Fits 2022-2026 Civic
Glossy black ABS
2-piece set
Peel and stick install
Pros
- Adds aggressive sporty look instantly
- Premium glossy black ABS material
- Protects original mirror covers
- Easy peel and stick installation
- Water and sun resistant
- Does not block BSD indicator
Cons
- Not compatible with Touring Sedan or Sport Touring Hatchback
- Adhesive needs pre-heating in cold weather
- Alignment during install requires patience
The CKE mirror covers are one of the fastest exterior styling upgrades you can do on a Civic Si. They install in about 15 minutes with peel-and-stick double-sided tape. The glossy black finish gives the mirrors a sportier profile that complements the dark accents already on the Si trim.
I appreciate that CKE designed these covers to not interfere with the Blind Spot Detection indicator light on the mirror. That is a detail that cheaper alternatives often overlook. The ABS material is water-resistant and sun-resistant, so the finish does not fade quickly.
Fitment covers the 2022 through 2026 Civic LX, EX, Sport, and Si Sedan, plus the LX, EX-L, and Sport Hatchback. The covers do not fit the Touring Sedan or Sport Touring Hatchback, so verify your trim before ordering.
The main challenge during installation is getting the alignment right on both mirrors. Take your time positioning each cover before committing to the adhesive. In cold weather, warm the tape and mirror surface with a hair dryer first for a secure bond.
Do These Come in Other Colors?
CKE offers this cover in glossy black as the primary option. The glossy black finish is designed to match the factory black trim pieces on the Sport and Si trims. If you want a different color, you would need to look at painted options from other brands, which typically cost significantly more.
Will They Fall Off at Highway Speeds?
When installed correctly on a properly cleaned surface, the covers hold firm at highway speeds and through car washes. The failures reported in reviews almost always trace back to installation in cold weather or on an unclean surface. Follow the prep steps and they stay put.
8. Xprite Window Visors Rain Guards – Best Ventilation Accessory
Xprite Window Visors Rain Guards Compatible with 2021-2026 11th Gen Honda Civic Sedan (FE) & Hatchback (FL1, FL4, FL5), Mugen-Style JDM Side Window Deflectors Vent Visor Shades, 4PCS
Fits 2021-2026 Civic
Mugen JDM style
Polycarbonate
4-piece set with hardware
Pros
- Mugen-style JDM design looks aggressive
- Polycarbonate resists cracking and UV
- Deflects rain with windows cracked
- Reduces wind noise
- Improves cabin ventilation
- Dual-fixation install system
Cons
- Fitment issues on some units
- Some report 2026 compatibility problems
- Clips may not fit all vehicles
The Xprite window visors bring a JDM Mugen-inspired look to the 11th gen Civic. Beyond aesthetics, they serve a practical purpose. You can crack your windows during rain to keep fresh air flowing without water coming inside. For daily drivers who like ventilation, this is a quality-of-life upgrade.
The polycarbonate construction resists cracking, fading, and UV damage better than cheaper acrylic visors. The dual-fixation system uses both snap clips and automotive-grade 3M adhesive tape for a secure mount. Everything you need comes in the box, including adhesion promoter pads.
I did notice some fitment inconsistency in the reviews. Most owners report a clean fit on 2021 through 2025 Civics. However, some buyers with 2026 models reported compatibility issues. If you have a 2026, reach out to the seller to confirm current fitment before purchasing.
The Mugen-style design sits closer to the window frame than in-channel visors, giving a sleeker profile. At highway speeds, they hold firm without vibration. Wind noise with cracked windows is noticeably reduced compared to running without visors.
Are These In-Channel or Tape-On?
These are tape-on visors with a dual-fixation system. They use both automotive-grade 3M adhesive tape along the top edge and snap clips that secure into the window channel. This combination provides a stronger hold than tape alone, which is why they hold up at highway speeds.
Do They Work on the Hatchback?
Yes. Xprite lists compatibility with the Civic Sedan FE, Hatchback FL1, Hybrid Hatchback FL4, and Type R FL5 from 2021 through 2026. The 4-piece set covers all four doors regardless of body style. Just verify your chassis code to ensure proper fitment.
9. AUTOXBERT LED Side Marker Lights – Best Lighting Upgrade for 10th Gen
AUTOXBERT LED Side Marker Lights for Honda Civic 10th Sport Si 2016-2021 Civic Coupe Sedan Hatchback Front Turn Signals Sequential Amber & White (Smoked Lens)
Fits 2016-2021 Civic Si
84 SMD LEDs
Sequential turn signals
IP67 waterproof
Smoked lens
Pros
- Smoked lens looks dark and aggressive
- 84 SMD LEDs for bright output
- Sequential amber and white turn signals
- IP67 waterproof rating
- Plug and play installation
- 58000 hour operating life
Cons
- Durability issues reported by some units
- May require wiring adjustment
- Some failures after 6 months
For 10th gen Civic Si owners, the AUTOXBERT LED side markers are one of the most impactful visual upgrades you can make. The smoked lens replaces the factory amber reflector with a dark, aggressive look that transforms the front end. During my testing, the 84 SMD LED chips lit up bright and clear.
The sequential turn signal function adds a modern touch. The lights switch between white running illumination and sequential amber turn signals. This switchback feature is something normally seen on much more expensive lighting kits.
Installation is true plug and play. You remove the factory side marker, unplug the connector, plug in the AUTOXBERT light, and snap it back into place. No wiring splicing or resistors needed for most vehicles. A few owners mentioned needing minor wiring adjustments, so be prepared for that possibility.
The one area of concern is long-term durability. While most owners are happy, a minority reported unit failures after approximately six months of use. The IP67 waterproof rating should handle weather exposure, but internal LED failures can still occur. Keep this in mind and check the return window when ordering.
Will These Throw a Code on the Dash?
For most 2016-2021 Civic Si models, these lights are true plug and play with no dash warnings. The LED load is designed to match factory expectations. If your specific model year is sensitive to LED changes, you may need resistors. Check owner forum threads for your exact year to confirm.
Do They Fit the 11th Gen Civic?
No. These side markers are specifically for the 10th gen Civic from 2016 through 2021, including the Si, Type R, Sport, and Touring trims. The 11th gen Civic uses a completely different side marker design and mounting system. If you have a 2022 or newer Civic Si, look for 11th gen specific LED options.
10. PERRIN Pitch Stop Mount Insert – Best Handling Mod for 10th Gen
PERRIN Pitch Stop Mount Insert Compatible with Honda Civic SI 2016-2020
Fits 2016-2020 Civic Si
Reduces wheel hop
Improves shift feel
5-year warranty
4 ounce insert
Pros
- Significantly reduces wheel hop on hard launches
- Tighter and more solid shifting feel
- Costs 15 percent of a full motor mount
- Does not add excessive vibration like solid mounts
- Basic tools installation
- 5-year warranty
Cons
- Increased vibration at idle can be intense
- Installation may require exhaust removal
- Bolt interference issues during install
- Only fits Si or Type R
The PERRIN pitch stop mount insert is one of those modifications that changes how the car feels without changing how it looks. It fills the gap in the factory rubber bushing that allows the engine to pitch forward under hard acceleration. On my first hard launch after installation, the difference was immediately obvious.
Wheel hop, that annoying bouncing you get when launching aggressively, is dramatically reduced. The drivetrain feels more connected to the chassis. Shifts feel crisper because the engine is not shifting around between gears. For the price, this is one of the best bang-for-buck performance mods for the 10th gen Si.
The trade-off is increased vibration at idle and low RPM. PERRIN designed this insert to add less NVH than a full solid motor mount, but you will feel the engine more. Some owners love the raw feeling. Others found it annoying and removed the insert. It comes down to personal tolerance.
Installation takes about 1.5 hours. Some owners reported needing to remove or lower the exhaust for better access. Bolt interference can be an issue, so having a decent socket set and some patience helps. The insert only fits the Si or Type R rear motor mount, not the base Civic.
How Much Vibration Does It Add?
The vibration increase is most noticeable at idle and when creeping in slow traffic. At highway speeds, the difference is barely perceptible. PERRIN specifically engineered this insert to be a middle ground between the soft factory bushing and a harsh solid mount. If you daily drive in heavy traffic, consider whether you can tolerate the extra feedback.
Can I Install This Myself?
If you have basic mechanical skills and a jack stand setup, yes. The insert itself is simple to understand. The challenge is access. You are working underneath the car near the rear motor mount. Having a second person to help position the exhaust or support components makes the job easier. Budget 1.5 to 2 hours for a first-time install.
11. Thenice Shark Fin Antenna Cover – Best Budget Exterior Accent
Thenice Car Antenna Shark Fin Cover for Honda Civic 2022-2026 -Black
Fits 2022-2026 Civic
Sporty shark fin design
Adhesive install
Premium plastic
Pros
- Perfect fit for 11th gen Civic
- Easy 2-minute installation
- Sporty unique design
- Holds through car washes and harsh weather
- Affordable upgrade
- Extra adhesive tape included
Cons
- Material quality is acceptable not premium
- Adhesive backing can be tricky during install
- May need extra tape for some vehicles
The Thenice shark fin antenna cover is one of those small touches that makes a big visual difference for very little money. It slips over the factory antenna base on the 11th gen Civic and transforms the roofline from standard to sporty. The install took me under two minutes.
The adhesive tape holds up well through car washes, rain, and sun exposure. Thenice includes extra tape in the package for owners who want an extra-secure fit. The premium plastic material resists high temperatures and cold, so it does not crack or warp through seasonal changes.
Beyond the Civic Si, this cover also fits the 2022 through 2026 Honda Accord and CR-V. So if your household has multiple newer Hondas, one purchase can dress up several vehicles. The piano black finish matches the black trim accents on the Sport and Si trims.
The only real downside is that the material quality is good but not premium. Up close, you can tell it is a cover rather than a factory shark fin antenna. From a few feet away, it blends in naturally with the Civic roofline.
Does It Affect Radio Reception?
No. The shark fin cover is purely decorative. It sits over the existing antenna without blocking or interfering with the signal. Owners confirmed that AM, FM, and satellite radio reception remains unchanged after installation.
How Do I Remove the Factory Antenna?
You do not need to remove the factory antenna. The Thenice cover is designed to fit over it using adhesive tape. Simply clean the antenna base, peel the adhesive backing, and press the shark fin cover into place. The whole process requires no tools.
12. TANDRIVE Key Fob Cover – Best Everyday Essential
TANDRIVE Key Fob Cover for (5 Buttons) Honda 2026 2025-2022 Civic Accord CR-V HR-V Pilot and 2026 Passport, Silicone, 2-Pack, Black
Fits 5-button Honda fob
Food-grade silicone
2-pack with chains
Fluorescent buttons
2022-2026 Honda
Pros
- Perfect fit for Honda 5-button key fobs
- Food-grade silicone feels premium
- Fluorescent buttons for night visibility
- Signal not affected by cover
- Includes 2 covers and 2 chains
- Multiple color options
Cons
- Key fob not included
- Silicone may attract lint and dust
The TANDRIVE key fob cover is the kind of accessory every Civic Si owner needs but rarely thinks about until their remote is already scratched. This 2-pack comes with two silicone covers and two key chains for an incredibly low price. The food-grade silicone feels soft and comfortable in hand.
I particularly like the fluorescent white buttons. They glow softly at night, making it easy to find the right button in the dark. The cover does not interfere with the key signal at all, so remote start, lock, and unlock all work at the same range as before.
The fit on the 5-button Honda key fob is perfect. It covers the 2022 through 2026 Civic, Accord, CR-V, HR-V, Pilot, and Passport remotes. If your household has multiple Honda vehicles, the 2-pack covers both daily drivers.
The silicone does tend to attract lint and dust from pockets. A quick rinse under water cleans it right up. The cover provides full scratch and wear protection for the fob, keeping the buttons and Honda logo looking new for years.
Which Honda Key Fobs Does It Fit?
The cover fits the 5-button Honda smart key fob used in the 2022 through 2026 Civic, Accord, CR-V, HR-V, Pilot, and the 2026 Passport. It does not fit older Honda fobs with fewer buttons or different shapes. Count your buttons and match the shape before ordering.
Does It Make the Fob Bulky?
The silicone layer is thin enough that the fob remains pocket-friendly. It adds minimal bulk compared to a bare fob. The included key chain is optional, so you can skip it if you prefer a slimmer profile in your pocket.
Buying Guide: How to Choose Honda Civic Si Accessories
Choosing the right accessories for your Civic Si comes down to four key factors. Get these right and you will spend your money on parts that actually fit and deliver value.
1. Know Your Generation: 10th Gen vs 11th Gen
This is the single biggest source of frustration for new Si owners. The 10th generation Civic Si covers model years 2017 through 2021. The 11th generation starts in 2022 and continues through the current model year. Parts are generally not interchangeable between generations.
Before buying any accessory, confirm your model year and check the product listing for explicit compatibility. A part listed for 2017-2021 will not fit a 2023 Si, and a 2022-2026 part will not work on a 2019 Si. This sounds obvious, but it is the most common mistake first-time buyers make.
2. Warranty-Safe vs Aftermarket Considerations
If your Civic Si is still under warranty, you probably want to know which accessories are safe to install. Cosmetic items like floor mats, key covers, sunshades, and exterior trim pieces have zero impact on your warranty. They are fully reversible and do not modify any vehicle systems.
Performance modifications sit in a different category. The Magnuson-Moss Warranty Act protects consumers by preventing manufacturers from voiding the entire warranty for an aftermarket part. However, a dealer can deny a specific warranty claim if they determine an aftermarket part caused the issue. Products like the K&N cold air intake are specifically designed and tested to work within factory parameters, which minimizes this risk.
3. Budget vs Premium Tradeoffs
Not every accessory needs to be the most expensive option. Some of the best value in this guide comes from budget items like the TANDRIVE key fob cover and the Thenice shark fin antenna. These deliver the same functional benefit as pricier alternatives.
Where premium spending makes sense is on items that directly affect your daily driving experience. LASFIT floor mats protect your carpet for years. A K&N intake improves how the car feels every time you press the gas pedal. The PERRIN pitch stop mount changes how the car launches. Spend more on the things you interact with daily.
4. Beginner Mod Ordering Roadmap
Based on forum discussions and owner experiences, here is the order most experienced Si owners recommend for first-year modifications. Start with protection items like floor mats and a sunshade in your first week. Add cosmetic exterior touches like mirror covers or a spoiler in the first month. Save performance mods like intakes and pitch stop mounts for after you have lived with the stock car for a while and understand what you want to improve.
For owners interested in deeper performance work, our guides on axle-back exhaust systems for the Civic Si and front lip splitters for the 11th gen Civic cover more involved upgrades.
FAQs
What are the best mods for the Civic Si?
The best starter mods for the Civic Si are all-weather floor mats for interior protection, a windshield sunshade for UV defense, and a cold air intake for performance gains. For handling, a pitch stop mount insert reduces wheel hop dramatically. Exterior favorites include mirror covers, a rear spoiler, and window visors for a sportier look.
What year Civic Si to stay away from?
The 2016 Civic Si was not produced in the US market as Honda transitioned between generations. Among the 10th gen cars, the 2017 model year had some early production teething issues with the 1.5L turbo engine, including oil dilution concerns in cold climates. The 11th gen Si from 2022 onward has been well-received with no widespread problems reported.
How much horsepower can you add to a Civic Si?
A typical bolt-on Civic Si with a cold air intake, cat-back exhaust, and a tune can see gains of 20 to 40 horsepower over stock. The Ku0026amp;N cold air intake alone provides a guaranteed increase, though the exact number depends on other modifications and whether the car has been tuned. More aggressive builds with bigger turbos and supporting mods can exceed 300 horsepower at the wheels.
What Honda Civic Si accessories are warranty safe?
Cosmetic accessories like floor mats, key covers, sunshades, screen protectors, and exterior trim pieces are completely warranty safe. Performance parts that are designed to work within factory parameters, such as the Ku0026amp;N cold air intake, are also generally safe. The Magnuson-Moss Warranty Act protects you from having your entire warranty voided for using aftermarket parts.
Is the 2026 Civic Si worth it?
The 2026 Civic Si continues the 11th generation platform with its 200 horsepower 1.5L turbo, limited-slip differential, and sport-tuned suspension. It remains one of the best value driver’s cars on the market. Accessory availability is strong for the 11th gen, with most 2022-2025 parts fitting the 2026 model. Verify fitment on specific items like window visors, as some products have not yet confirmed 2026 compatibility.
Conclusion
Finding the best Honda Civic Si accessories does not have to be overwhelming. Start with protection items like the LASFIT floor mats and the EcoNour sunshade. Add the exterior touches that match your style, whether that is a Femibon rear spoiler or CKE mirror covers. Then move into performance territory with a K&N cold air intake or PERRIN pitch stop mount when you are ready.
The accessories in this guide cover both 10th gen and 11th gen Civic Si models, so whatever year you drive, there is something here for you. Always verify fitment before ordering, prioritize warranty-safe mods if your car is new, and tackle accessories in the order that matches your driving needs. Your Civic Si is already a great car, and the right accessories just make it better.
