    • Nice
Easy to install, good sound, little more power

    • Great product
The media could not be loaded. Intake fit perfectly in my 2019 Honda Civic Sport 2.0l. Directions were accurate and pretty easy to follow. Makes my car sounds way better and makes engine bay look cleaner. Did notice a slight increase in horsepower.

    • Very Impressed
I purchased this intake when it was on sale for $279.99. The kit included everything needed for a proper install. The included directions are very clear and concise. Cold starts, and normal driving do not sound any different than the factory air box; very quiet, livable, and under the radar. However, under wide open throttle there’s a peak in intake noise around 3’500RPM and again above 6’000RPM. This is an excellent option for someone looking for more volume out of their K20 civic, AND do not like how exhaust modifications sound on this drivetrain. ... show more

    • Easy install, no problems
Great intake. Did not need a tune, had decent IATs and sounded amazing. Could hear it from miles away. Easy install if you follow the instructions and everything fit great. I’d recommend PRLs piping + filter with the OEM housing for better value and performance though.

    • Sounds amazing!!!
Review Image by Jared B. Jared B.
Great product, sounds amazing, I recommend getting ktuner to go along with this, because by itself you will only hear a sound difference, but with both you can feel the difference. Don't get this intake because you think it will change the way your car drives, no, no it will not, it just sounds cool. If you get a ktuner, it will sound cool and perform better! 5 star ... show more

    • Actually has a nice tone

I’m liking this K&N intake was pretty easy to put together and install in the Civic. Sounds great, Just be prepared that taking the old filter box out is an absolute pain.

    • Does exactly what is says.
When you own the manual transmission and control engine rpm yourself, the difference is obvious. This intake sounds amazing. Pretty the reviews that say it doesn't sound good drive the CVT automatic version. Again it sounds great and has a small but noticeable power gain. For what's on the market as far as intakes go for this civic, this was definitely the best option. ... show more
