    • 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. ... show more

    • Great suction!
When I finally got the end in, the amount of suction on the tip changed. I could definitely feel it open up. If you want your engine to suck much better, get K&N

    • 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.

    • 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
