There’s no better feeling than showing up to the local meet, popping the hood, and showing off the new "go-fast" parts.

Add the satisfaction that those "go-fast" parts in your Honda Civic’s engine bay are more than just eye-candy and you'll be loving you car all over again. Get the details below and dare to Redefine.


Our unique airbox design pulls cool ambient air from the fender well just like a typical CAI system, but without all the negatives of locating the air filter in the fender well. No more worrying about hydro-locking or tedious filter maintenance.


With the unique airbox design, accessing the air filter is a quick and easy process, because the air filter is now located up high in the engine bay just behind the smoke tint cover, Standard maintenance is now a simple task without the need to jack the car up and remove any fender liner to access the filter.


There are no compromises with the 27WON Cold Air Intake, not even the hardware and accessories. All hardware, brackets and T-Bolt clamps are manufactured from stainless steel. Yes, we said T-Bolt clamps…no worm gear clamps here.

What's a Cold Air Box without the data to back it up? Here you see the intake air temperature measured at the MAF sensor for the OE intake system vs the 27WON Cold Air Intake System. Not only is there a difference of nearly 15 degrees F, but the 27WON CAI also increases to source cooler air as the vehicle speed increases.


We understand that poor fitment and installation is frustrating, that’s why we have designed the 27WON Intake System to fit and install without issue AND does not require the modification of any OEM parts.


Increased flow is always the key to enhancing the performance of your engine. The 27WON CAI takes in cool air from the fender well, filters it through a high flow non-oiled filter media, and through the seamless silicone and billet MAF for a system that’s designed to work together for the best performance.


Smooth laminar flow is critical to get the most out of the stock size intake system. Seamless connections between the airbox, silicone, and MAF housing eliminate the abrupt edges that cause turbulence and inefficiencies in the intake system,

Installing Your Performance Cold Air Intake System

You get what you pay for and this is no exception. Superior intake system which was easy to install thanks to the detailed instructions provided by 27WON. Paired with my new exhaust system, I am happy with this CAI upgrade. I'll give a shout out to Vincent as well - Received great customer service when I noticed a minor issue with the filter cover. Vincent is on top of his stuff and stands by his products.
The quality of this intake system is the best I've ever seen and there isn't anything close to this on the market. Installation was a breeze with the hardest part being removal and installation of the bottom tray. Just follow the very detailed instructions and you'll have no problem installing this intake. I can't wait to purchase more quality products from 27Won.
Getting the products overseas is a bit more difficult but it is definitely worth the trouble as the quality is second to none. I'm loving the way the car breathes now and all the sounds that come with it. You can really feel the difference against the stock box. This is probably the best intake for the Civic 10th... in the world.

I definitely recommend it. Keep redifining the aftermarket.

Keep it up, guys! Greetings from Spain.
Great intake, first time installing was a breeze for sure. Any questions you can always call and Vincent himself will pick up and answer everything for you with no hesitation. Great customer service and a great product in all.
To start, when I opened the box, first thing I saw was a cool little hot wheels civic, a keychain, and some cool little stickers to put on my car. Which alone surprised me, an made me feel as if they care about their customers more than some of these other companies. When I picked up the intake itself, it was for sure no question made with some good quality material, and they even go as far as putting a plastic film to protect your box the filter sits in. Have not yet installed, but I know I wont be disappointed. No, I am not being paid to write this review or benefiting in anyway lmao
Installation was a breeze with the best instructions I've seen in a long time. Product quality and fitment is great. Seat of pants dyno, seems to be a bit more responsive, pulls a little harder, and slight increase in turbo noise. A+
Hands down amazing product! quality parts and hardware, the installation was a breeze and it looks so good in the engine bay definitely my favorite piece to the car.
Just dropped it in today. The instructions were amazingly clear and it fit perfectly. I went out on a test drive and was amazed at the new turbo noises I get to hear! Pulling through some corners I can feel better torque and more power on the top end. Oh, and did I mention how fun the extra turbo noises are?? Hey Vincent, you and the team made a hell of a product; keep up the good work I’m now a loyal customer.
Excellent packaging. Great easy to follow instructions. Took just over an hour to install, most of it spent removing OEM parts.

Test drive showed excellent numbers; STFT (+/- 5%) and LTFT around 0%. Temps definitely lower than OEM at speed.

Thank you 27Won!
Got my intake a few days ago. Just got it installed earlier. And oh my!! Love that you can hear the turbo more and most definitely can feel an increase in power!! Super excited for this. Next I'm thinking about that rmm!! I'll be a customer for you guys for a while. Love supporting a small business!! Thanks again guys!!!!
