Michael Hall, Chateauguay, Canada
The filter received was damaged, but outstanding service to send me a replacement within 4 days. The replacement filter was a perfect fit for my S2000.
Heidi Le, San Diego, California
I usually drive my car everyday, so I bought an extra one for back-up for when I need to degrease and clean my other K&N air filter. So far so good. I haven't installed the new one yet because it came in two days after I cleaned my old one, but I'm sure it'll be super nice.
Ven De La Garza, North Carolina
In all honesty, I really can't say for certain if the product really made a difference. I have done numerous improvements to get my car up to top performance and felt it deserved arguably the best air filter money can by. So I joined the club of other performance driver's to purchase a K&N filter for my vehicle. Can't beat the quality.
