K&N 33-2439 Air Filter Product Reviews

Friday, June 15, 2018 - Part 33-2439
Hello Mike I like your products they are well built and last long I have your air filter on both my vehicles. I lease my gm terrain and wish I would have bought your filter as soon as I began my lease because I wouldn't have had to pay the dealer $60 for a regular paper filter which is more expensive than buying from you direct.i also enjoy the extra performance from I get from my vehicles with your product's. Thank you Joseph Ferreyra
