Cold Air Intake System: High-Flow Air Filter, Increase Performance & Acceleration: Compatible with 2016-2021 HONDA: Civic, 63-3516

Easy install. I did it with simple hand-tools and it took me about an hour and a half to install by myself. I never installed any intake before, so I’d say it’s super easy. The hardest part was literally taking off one bolt that held the old intake down, but it would’ve been easier if I had a longer ratchet extension. The motor looks cooler, sounds insanely better, and performs better. I instantly noticed the turbo is able to deliver boost a lot faster, almost instantly. Also the gas mileage is even better. This is a win-win upgrade.

I’ve only ever heard good things about this air intake & it precedes its reputation! I originally only hair a muffler & resonator delete so my car was already loud. Without saying this made the sound better and the performance is better. The quality is good, the price is great compared to other, and it adds some color under the hood. It was a also a quick installation and fits perfectly fine.

Does everything Id expect a high end CAI to do. Install was simple enough, worst part would be needing an extension to get to the 2 bolts for removing the old airbox. MAKE SURE to disconnect the negative battery terminal for a bit, this way the ECU needs to relearn and adjust to this or it'll throw codes. Driving definitively feels snappier on the throttle, power is there, and after week of driving my average MPG of 33-35 went to around 37-38. Could just be old filter was a bit dirty too when I saw it after. The sound is pretty great, could barley hear the turbo before, but now opening up the throttle it is loud and apparent. More of throaty motor noise too. As for value, its up to you if 10-12 hp/torque/better mpg is worth $300 to you.

Do not buy this product and do not let anyone else buy it, the vehicle does not accept it.

Just installed this on my 2018 Honda Civic about 2 hours ago. Install went pretty smooth and straight forward. You can really hear the turbo spool up, a lot louder than I was expecting but I love it! Only problem was getting the stock airbox out. You just have to pull until it comes out after removing the two bolts. We'll see how things are in the future but right now its amazing.

Drastically improved acceleration on my 2017 Civic Sport. I have the CVT transmission and it still sounds great especially when doing a small pull off a stop light or something. Great growl sound and big whoosh when you let off the throttle at about 4000-5000 rpm’s

Although I though that K&N was overcharging for this intake, it does everything a performance intake system is supposed to do. Better engine sound, you can hear the turbo, it increases acceleration (You will feel a difference!), and will eventually provide even better full economy (when you're not mashing the gas). Some people say that these do nothing for fuel economy, that is false. This is my 4th K&N intake system and the first three I have found that it takes about 500 miles for the computer to accurately state the MPG. Don't expect anything major, probably 1 or 2 mpg. Update 9/7/2020: After moving to Florida I noticed the intake began to heat soak when as my IAT's were above what the stock airbox was. I quickly realized that this intake had zero benefit in hot weather and I decided to sell it. Still enjoyed the intake and would've kept it if I was still in Indiana but living in Florida I will be buying the 27Won Hybrid CAI to lower my IAT's.

I have a 2018 Honda Civic Hatchback Sport CVT. I installed this CAI to complement a Magnaflow 19373 Cat-Back exhaust and a Ktuner with Phearable 1.5R tune. Idk how the CAI performs individually, but at 5k+ RPM, my car is roaring and pulls like a little beast. This CAI opens up the possibility for more power, but the induction sound is definitely more pronounced. The only bad thing is it will heat soak after just minutes of daily driving. I’ve seen numbers as high as 60F above ambient in stop-and-go traffic—and that was just the air going into the intake—the air temp at the inlet pipe is going to be MUCH higher. I tried wrapping the CAI housing and tubing with reflective tape and asbestos wrapping, but I don’t think that helped at all. Still had the same temps. Our L15-series engines run notoriously hot. You will lose boost repeatability if not driving in the highway or have an aftermarket front-mount intercooler (FMIC). This is not the CAI’s fault, but rather the Honda engineers’ for not putting a larger factory FMIC. (To be fair though, all Civics except the CTR were created as economy cars.) To counter this heat-soak issue, get a FMIC. I don’t have one myself, but check all the serious CivicX forums and they’ll tell you 27Won and PRL make the best FMICs. That’s my next mod. Bottom line: don’t sleep on this product—get one! PS: A lot of people will champion the PRL Cobra CAI, but remember the filter will only sit mere inches from the ground. If you live in a swampy area or an area that sees heavy rainfall or floods, I wouldn’t recommend it—even with a moisture sock. You do you though.

A superbly easy kit to fit. The instructions were comprehensive and well illustrated. And this resulted in a noticeable increase in acceleration, with the nice benefit of some ‘growl’ when you put your foot down. A highly recommended upgrade.

Aumento de sonido a partir de 4000 vueltas es más ronco y más potencia

I wish I had bought this ages ago. I had a regular k&n filter in the factory air box for about 240,000km thinking it was great. I decided I would start tinkering with the car and after installing the cold air intake, I immediately noticed a more throaty sound, louder turbo and blow off from about 2000rpm onwards when accelerating. Without even a new map, the power band has smoothed out very nicely and pulls noticeably better past 4000rpm. It is also way more responsive, has less turbo lag/quicker spooling between shifts, and about 1 liter/100km of better fuel economy so far. Highly recommend as a great value to compliment any other mods and to get your civics turbo breathing freely.

Tolles Ansauggeräusch gegenüber Serie.

Le queda muy bien al mi Civic sport coupe + 2019
