Great product, fast shipping. I have bought K&N filters my whole life and never had a problem with different vehicles that had K&N on.

I have been a professional Race Team Tech, Manager and Crew Chief for over 40 years. I have also been using your products since the mid 1970's on every conceivable race car imaginable and my personal street cars as well. I will never use another filter besides K&N. It's just not worth the hassle! Thanks for your products! They are always above the norm! Charles.
