K&N 33-5045 Air Filter Product Reviews

Tuesday, October 17, 2017 - Part 33-5045
This is my first time purchasing a K&N filter and I am very happy with my purchase. My car 2016 Civic (2.0L engine) definitely drives and performs better. Would mostly return to K&N products for any future purchases.

I put this air filter in my wife's Honda Civic 2017. We get at least 10 more miles per gallon. At least! Very happy with it.

No matter what car I drive (and I've own 6 so far), I will always have K&N in it... dependable and very long lasting, it out performs what you would expect from just a simple air filter.

Simply awesome. This filter gave my already high MPG a boost. Glad to be apart of the K&N way now.
