The filter was extremely easy to install. I have noticed a 2MPG increase already with the K&N air filter.

I always trust K&N when it comes to quality filters. I installed this filter around 15K in my new 2012 Honda Civic and after a month I noticed I get 2 miles more to the gallon. Quality and performance, trust K&N.

I just installed this in my 2013 Civic EX. Instantly improved my gas mileage by 3 to 4 MPG. I have had a K&N filter in my 2001 GMC Sierra for the last 180,000 miles and it is still going strong.
