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 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.

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
  • 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

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*

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

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,

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.

It was a fun experience to install it with my coworker KD. Without a doubt worth the money to spend on for a first mod. An you can hear and feel the difference thank you 27won
I really didn't want an open-air short ram, and had some concerns with other cold-air filter locations, given the weather in my area. The 27won intake fit my purpose and requirements perfectly! I had previously installed a PRL stage 1 kit (better filter and hose out of intake box); and the sound difference is definitely noticeable and impressive, in my opinion. IATs are much better, as well.
Installation was a breeze, thanks to the awesome instructions and a plethora of youtube videos that show some shortcuts from the already streamlined installation process.
Can't recommend this intake enough!
Great quality was put in to this intake. Only thing better than the quality of 27won is the customer service. Extremely professional and super friendly and helpful. Btw install was a breeze with amazing instructions. Thank you 27won team.
Very good quality and the customer experience is also very good, quick response to all your questions thumbs up to vlad.
Now about the cai itself i definitely feel a difference especially in acceleration the engine can breathe better the noise is not extreme but this is just what i was looking for.The instruction manual is very detailed i think anyone with a bit of experience can do this. Finally very satisfied with my purchase.
Installation is not that hard, but for CVT is a bit tricky. The Airbox needs to be aligned correctly so it won't touch the CVT sensor. The slit on the airbox lid caused heat air to get sucked, however this can be fixed by closing it with tape. Between the lid and airbox can be improved by adding a rubber seal, to secure from vacuum leak. Overall I can feel the power at any RPM and definitely define the meaning of CAI. Very happy with the product. Gave them 5 stars.
This CAI is perfect in every way! The sound it provides for the turbo is so much better than stock! Really makes it stand out! Would highly recommend getting this! Paired with the TIP and the W1 Turbo the sound is so good.
At the time I bought this intake it was the first part to go on my cold side. Apart from the peske lower bolt for the OEM air box (which is in no way 27Won's fault) installation was simple. Also got the bigger MAF housing with mine as well and after throwing the shelf tune at it all was well and good.

Increased Induction noise from the turbo was very apparent even at lower boost levels, and with the stock turbo inlet you even get a decent BPV noise.

Honestly, just the concept of a cool air intake that is still easily serviceable is enough to put this intake at or near the top of the options. But the ease of install and resulting clean look under the hood makes this a no Brainer buy.
Installed the intake a few months ago, gotta say, there is a good reason everyone I asked would suggest this and PRL. The quality is great, sounds great, just all around completely worth it! Also, customer service is top notch.
Really easy install, gives a fair bit more power. Highly recommend getting the race MAF if you can also get a hondata.
Best looking intake. Excellent fit and finish. Installation takes a bit of time but it's worth it. Also customer service is second to none. Thanks Vincent Vlad and all the people at 27WON.
