There’s no better feeling than showing up to the local meet, popping the hood, and showing off the new "go-fast" parts.

Add the satisfaction that those "go-fast" parts in your Honda Civic’s engine bay are more than just eye-candy and you'll be loving you car all over again. Get the details below and dare to Redefine.


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 smoke 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.


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.


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.


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,

Installing Your Performance Cold Air Intake System

Difficulty: 2/5

2/5 Difficulty




This intake sounds great and is effective at cooling the motor under acceleration. Temps rise quick in traffic but once you get that turbo spooling you can see temps drop 30 degrees in less that one minute. This intake loves boost and makes that “psssshhhh” turbo noise we all love. The hybrid design makes maintaining it a breeze and that install can be done in 15 minutes for the mechanically inclined.
This intake is being amazing!!!! I love it and I would recommend it any day! The phrase you get what you pay for is true!! Don't let the price scare you away or you will be missing out on something that is built incredibly well ????????
had this intake installed since Nov 2018, so far loving it, definitely notice the gain in torque/hps immediately and i can full throttle till redline without losing power. Install is easy and imo the best looking CAI in the market for the 10th gen civic so far.
Honestly as a first time installing a intake, the instructions says it all. Literally step by step, such an easy installation. Not to mention the difference in torque you feel when stepping on the pedal is such a noticeable difference from the oem air box. I’m glad I made the decision with the 27won intake.
Likely the best cold air intake on the market right now for 10th gen civics. Gives great sounds, noticeable power and acceleration gains. Perfect fit and easy install. Highly recommend.
These guys provide awesome customer service as well as having top of the line products. Definitely looking forward to installing the intake and having better airflow. Thanks guys at 27WON!
Honestly the best CAI in the market for Honda by Redefining what cold air intake really is. First and foremost the intake system has the filter running on top in an enclosed box that is made with special plastics to reject heat. Next is in the box runs a tube-like connection that goes down into the fender well to pull true cold air like any CAI would except not needing to have the filter down in there for risk of hydro locking. My fuel trims are practically perfect now and can feel that extra whp and wtq without a tune but will get that custom tune soon. Anyways best intake in the Honda game and 27Won is truly redefining the aftermarket!
