27won design logo

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.

27won airbox graphic

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 black 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.

27won hardware graphic

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.

27won advisory graphic
  • Installation of the 80mm RACE MAF will require scaling of the Mass Airflow tables. It is highly suggested you contact a local tuning professional to help you perform this function. Street MAF does not require tuning
  • A Hondata Flashpro, KTuner, or stanaldone ECU is required to perform MAF scaling. It cannot be performed on a stock non-flashed ECU
  • The 27WON 80mm race MAF is designed to work with the 27WON Hybrid CAI only
  • CVT users, note the tight tolerances between the airbox and CVT oil pressure sensor during install. The sensor will abut the airbox
  • Fitment of 27WON intake with a PRL FMIC kit will have slight contact on lower portion of airbox due to FMIC pipe routing. You can place some thick tape between 27WON airbox and the PRL cold pipe to mitigate the interference. Click here for a reference image

27won fitment graphic

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. *Will not fit CVT cars equipped with aftermarket CVT fluid coolers installed*

27won MAF graphic

Make even more power with our optional 80mm Race MAF upgrade. Built with the same precision machining as our Street MAF, the larger Race version allows you to flow even more air in the pursit of more power. Learn more about why you could use this upgrade here.

***Note*** Tune is required to run Race MAF

27won air flow graphic

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,

27won breathe easy graphic

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.

bundle and save

You’ve asked, we’ve delivered. Bundle and save. For a limited time, when you add both a 27WON Intake and Turbo Inlet Pipe to your cart, you’ll save over $70.00 on your order. Discount taken at checkout.

Proven time and time again, pairing a 27WON Cold Air Intake with the largest Turbo Inlet Pipe on the market for the 1.5T L15 maximizes the gains you’ll see. We’ve seen as much as an additional 9HP when running a full suite of bolt ons and an upgraded turbocharger by adding this inlet pipe. Plus, have you seen how much better it looks compared to your stock flat pancake looking pipe?

Installing Your Performance Cold Air Intake System

Difficulty: 2/5

purchased the si catback exhaust and i got to say it’s amazing. Sounds amazing looks amazing no other way to describe it. Vincent helped me through out the whole order and i got the exhaust the same day he said i should receive it. Took one week for me to get it.
It was on back order when I ordered mine, Vincent followed up on it and I got it a week ealier. Easy install.
The Dozuki app made the already simple install that much better. Fit, Finish on the intake are great. Not super loud, which is what I wanted. No complaints at all. You can hear it in car but wont wake the neighborhood.
First product bought for my 10th gen and don't regret it at all. Sound is nice and appearance in the engine bay is clean and looks like it belongs there. There is a small fitment issue with the the silicon boots but perfect fit is always hard with mass produced parts. Just a heads up to candian shoppers, if you don't use a cross border shipping firm you will be hit hard with duties. Overall a great product and will be saving up for my next 27won purchase.

Have the 27won intake installed! Sound is improved over stock and I've driven this car through some torrential rain and had no issues with the water. All the hoses fit tight and it's looks very clean under the hood. I might switch my MAF sensor housing to black at a later date to match with future parts better. Very pleased with the intake and the customer service at 27won is second to none! Vincent has been great to deal with and very helpful as is have asked alot of questions leading up to my current purchases. More to come as im very happy with the product and service from 27won.
Patiently waited for it with Vincent contacting me with updates about shipment, which goes to show how Great his customer service is! Installed it the day I received it with just some ramps, no jack and a basic tool set. Super easy with the perfect fitment! No issues! Can't wait to purchase the FULL exhaust when available! Thanks Vincent and 27won team!
Install was easy, however for your first time taking off the skid plate, USE A LIFT lol. If you are experienced, use jack and jack stands and only take off the drive side of the skid plate. I took 30-40 minute just taking off the skid plate as this was my first time locating all of the plastic parts. All in all, if you installed these frequently, its pretty easy. The hose clamps were a bit of a struggle. I think I was sent 2 of them that was the wrong size, however the matter, I was able to install them with some help of some geese. All is good, the quality is there, the proof of cooler temps is there. AT MOST, I saw 107f from light to light. This is in a 45mph zone. Very good 27won!!!
Love my Intake! Can definitely hear the turbo spooling up and still gets that nice Blow off sound after releasing the throttle on boost. Huge shout out to Vincent. Kept me in the loop with my product. Crazy to receive calls from him! Just shows me what kind of company they are. I will definitely continue to buy 27Won parts.
This is one of the best intakes available on the market and I highly recommend it to anyone looking for an upgrade! I have a CVT so the installation was a little difficult, but it fits well and the turbo sounds are amazing. I also want to give a shout out to Vincent for amazing customer support when I had a blemish on my lid from the factory. He was fast to respond and replace it accordingly.
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.
