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

2/5 Difficulty




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.
Best bang for your buck. Easy install and great look under the hood. There is definitely a noticeable increase in throttle response and performance. Would recommend to anyone looking for a intake for their 10th gen si.
I've had this intake for several months. I love how it solves all the problems with Short Ram Air intakes and traditional Cold Air Intakes. The engineering and quality are top notch. The performance is noticeable. I also really appreciate that this company makes parts for all the Civic trim levels instead of just the Type R and Si. The customer service is excellent (thanks Vlad!) and I'm really looking forward to my next 27won part! (Please make more W1 turbos!!) :-)
So I'm in my 40's, and only recently started getting the itch to learn more about cars. I got a Honda Civic EX earlier this year, and have been obsessing over what I could do to tinker with it.

Thanks to Vlad, I got all sorted out, and installed a new cold air intake today with a buddy of mine. We had a blast, the cai looks sick, and I couldn't be happier.
Wow! This is a part of heaven on my Civic! I have to say i used to buying cheap parts from ebay so I was unsure of spending that amount of money on an intake but... IT IS WORTH EVERY PENNY! I will never buy cheap again! During installation, everything is bolt on (not almost bolt on: BOLT RIGHT ON! :)and you get full install guides. You feel the quality of the parts, strong and solid, and the results are there at the end. and the sound it bring to my "used to be silent" SI is so perfect! thanks will buy again!
Love my 27won CAI! I've had the intake for a couple months now and you can actually hear the turbo suck in air and the blow off noise. I live in Seattle so this style of Cold air gives me peace of mind that I wont suck in water and hydrolock my engine. Great build Quality and packaging made it feel like you were getting something special. Noticed my intake temps were slightly lower too, which is a bonus.
You can tell right away the quality and care that goes in to these parts. Happy to be a part of the 27won fam
