Customer Feedback

This product is so good . My 2015 Honda Civic performs much better. I feel my engine is more powerful and its loud.

Love these people. I have a 2002 Jeep Wrangler that the code No. was unable to be read for smogging. Had to take a picture of unit installed on Jeep and they sent me out a new number the next day. I now have K&N on 2002 Jeep, 2013 Honda Civic including cabin filter and just purchased for 2013 CRF250L motor cycle. Now days you can't beat the price. They pay for themselves. When I say love these people, it takes good people to make a good company. Love you guy's.......and gal's! Thanks a 1,000,000! Kevin

Its my second K&N intake kit. I had one for a 2004 Honda Civic but this one on my 2007 does not compare. The sound is crazy and the power you get; you can feel the difference.
