The best air filter money can buy.
Bill Anderson, White Plains, New York
Observed a discernible difference in performance, mostly above 4,000 rpm...on cool mornings, pulled strongly to over 6,000 rpm.
Matthew Lyon, West Haven, Utah
It accelerates like a turbo'd car now - - sounds great. I'm impressed and feel bad I didn't do this earlier. Looking forward to purchasing and using additional K&N products.
