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

LOVE this intake. Looks clean and sounds great. Customer service is also on point. If you're on the edge, do yourself a favor and buy this beast!
One word.. Unbelievable!
Installation was very simple, online guide helped every step of the way! Craftsmanship was beyond professional and you can really feel the engine open up more, really being able to breathe!
Thank goodness for YouTube and the best instructions I have ever seen. Install was seamless. I love the way that my 2020 Si sounds now. You can definitely feel the difference. Love the way the engine bay looks now when you pop the hood. Fit and finish were spot on. Did a bit of research before making this purchase and I can honestly say I am not disappointed. If someone tells you that all CAI are basically the same >> smile and politely turn around.
I absolutely love the 27won intake. Everything from the looks to the performance. I couldn’t be more happy with all of the parts I have bought from the best guys in the aftermarket parts scene.
This Intake is honestly so nice fresh, and felt like it made a difference in mid range. love the quality and look / design. CVT users beware of oem lower intake box. its a pain to take out
The wait was definitely worth it for this intake! Fitment was spot on and installation was a breeze.
On a stock tune fk7 sport manual the good ol' butt dyno feels like there's a bit more pull through the whole rpm range. (Even chirped my tires shifting from first to second first time today since owning the car for 6 months) And a noticeable throttle response difference. Not to mention now there's that oh so satisfying sound of the intake doing it's job and getting that sweet sweet cold air in. Can't wait until I get a tune and fully unlock it's potential.

Shout out to Vincent and the rest of the 27 team for creating such great products for the 10th gens. And also a massive shout out and thank you to Vlad! Y'all have an awesome employee on hand and probably one of the best and most responsive CS reps I've seen!
I made this part of my 27won haul for this summer and its amazing, just like everything else it was easy to install and puts a smile on my face. Vincent and Vlad are absolute legends, gave me all the info I needed and provided great customer service.
I chose to purchase this intake over other competitive intakes due to the fact that 27won goes the extra mile with additional engineering and development it takes and required to achieve a successful high performance platform. These steps speak volume about this company. They are not in the market to make money selling products they are here to ensure we have the right tools it takes to achieve success. The true question is not is this a great product? It is how can one find the funds to install all their products. They're not here for a good time they're here for a long time. Kudos.
This intake is far superb over anything on the market and think about this you're driving on the highway after a rain storm and what you thought was a thin layer turned out to be inches of water that just sucked up your cold air intake and blew your motor. This company obviously cares about our engines and our future.
Awesome intake! Couldn't be happier. Looks and performance is spot on. Why anyone would even consider other brands like PRL is beyond comprehension. Air temp are much cooler an can feel a boost hp increase.
Great intake, great quality too. Love the way it looks and the sound of the BOV in between shifts!!!
