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
  • 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.

Installing Your Performance Cold Air Intake System

Well Designed, looks and sounds good. What else is there to say!
Solid product, Vlad was awesome during the process. Will definitely be purchasing more products when available. Installation wasn't terrible but taking the skid tray out was not a great time haha
Installed this with the inlet pipe. Everything from packaging to parts is top notch. Reached out through email before my purchase and Vlad was very helpful. Took me a good 6 hours to install both. Will definitely be purchasing more from the 27won team. Whoooosh!
Looks great under the hood. Can hear turbo noises often. Slightly better air temperatures. Throttle response seems a tad better with TSP stage 1+. Install kind of sucked removing the undertray but not 27WON's fault. The instructions were decent, but when installing the airbox one step requires you to somehow put a bolt in like 12 inches down into a tight space, whereas installing that bolt first and then doing the rest was a lot easier. Overall, pretty satisfied.
Install was a tad bit more on the medium side for me but after a couple scratches and cuts...its wow, I'm amazed...okay it's not loud so don't expect to hear loud but....BUT....this CAI well worth it if your looking for that in-between...instant wake up for the engine you can just feel it more air...and I mean this 1.5 wakes up feels like a new ride and yess you still here the psssshhh...to me it's awesome. Well done 27won!
Works nicely! Easy install, no codes, and comes with subtle turbo noises. Good product for the money, no impressive gains on stock maf, but looks great under the hood.
Amazing quality product, and fitment was spot on. The step by step instructions were spot on and made it effortless to install. 27WON is setting the bar high and their customer service is bar none. These guys are here for the long haul. I am a 27WON believer . Can’t wait to continue buying more products from you guys for my FK7 and FK8 platform.
this cold air intake with 27won’s full cattles downpipe and full exhaust system, together they do magic. amazing product
Love the CAI, you can hear a bit of a difference too now. Love the style, plan on getting more from 27won. Thanks for redefining the aftermarket!!
This CAI is just absolutely the best way you can go! Top Notch design. The fitment, the gains, the look and the sound were exactly what I was looking for. Together with the best quality I have ever saw until now, this is just amazing! I would like to send a shout out to Mr. Melon for taking Gen X innovation to the next Level!! Keep up the success of your team family at 27WON!

Special kudos for Vlad! You Rock buddy. Thanks for all your advices.
