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.

  • 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.


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.

Installing Your Performance Cold Air Intake System

This product is just flawless. Really, 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 product.
Fits manual fk7 international model without any problem. Recommended!!!
I installed this intake along with the turbo inlet pipe. The first thing I noticed was the sense of urgency the engine had when driving in lower RPM's. The throttle response, low end torque and turbo spool all received a noticeable improvement. Mid range and top end pulls were also improved. A simple roll on the throttle at freeway speeds delivered excellent passing power without having it in sport mode. I anticipate the arrival of the recently ordered race MAF housing and downloading some new maps with the Ktuner. I feel this was a great start to the build and will compliment the downpipe and exhaust when they are installed in the coming weeks.

So my wife got me this CAI from 27won as a birthday gift. Due to COVID-19 came a little later than expected but the wait was more worth it. Shout out to VLAD with the excellent customer service keeping updates on the shipment. Packaging and presentation is nice.(I may be a stickler but I love that stuff, gives you a premium feel to show their craftsmanship) Install was a breeze due to expert write ups on instructions. I picked up this intake over other intakes because of the drop in / feature and its engineering and design with also being able to service the filter without taking off the bumper. Sound; in my opinion is good when your daily driving (you hear it).. but when you are on the throttle past 3500rpms; (you hear and feel it) (on a stock tune 2018 civic si sedan) when shifting that whoosh is apparent enough to put a smile on your face :). Looking forward to working with you guys again with the build of our SI. And Thank you to VLAD and the Team at 27won. REDEFINE
Is it available in the Canada market?. Thx
Great product and perfect fit. Very pleased
Great intake and great customer service!
This intake is so good! I love hearing more of that turbo, makes the car so much more fun to drive. Everything fit perfect and the instructions are so easy to follow. It also looks really nice under the hood and i like that the filter is easily accessible to clean. Definitely well worth the price, i love it!
Awesome intake! It was super easy to install and I absolutely LOVE the sound. The product quality was also very good. 10/10
Already had the downpipe and engine mount, and knew that the only CAI my car was getting was the 27won, I checked all the options just in case but this one looks/feels/fit better no matter how u look at it.
I love this intake. I bought it bcz I live in a tropical island where it always rains and floods a lot. This intake has the best of both worlds, the benefit of cold air as a cai and you don't have to worry of sucking water as a short ram.
