Good product overall
My mpg went from 35 to almost 40 mpg. It sounds great and works even better. It was really easy and simple to install and I'm glad I bought this. I drive an half an hour to school and from school everyday so for me it was worth it's price. I don't think you can make your Honda that much faster with this air filter but it sure is great for its benefits. The airflow seems great, you can really hear it going 0-30 mph.

Perfect fitment
A piece of cake to install. Installed in my driveway with minimal tools. Anybody can install this plug and play. Sounds awesome, looks great and has great build quality.

I should have chose this sooner
This thing really woke my car up! Nice low growl but not like those annoying straight pipe cars. When I litter go off the accelerator she’s right back to being quiet. The throttle response is amazing. I only need my big toe to drive. Speed increases without trying.

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.

Muy buena compra

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.
