Product Reviews

 Although the air flow specs on filter is less than a canister type, the quality is unsurpassed. When my brothers filter wore out, you sent him a new one. Your reputation speaks for itself....Thank you

 Perfect fit in the GTi factory air box - looking forward to better breathing.

 I will always put your filters in my cars, and my kids' cars. I maintain my vehicles very well. K&N is an important part of that. Money well spent. Thank you for the great products and service.

 Installed the new K&N filter in my 2005 VW Golf TDi.
First tank, fuel mileage improved from 42 to 45 MPG!
Thanks K & N.
