After I buy a new car, the first thing I do is swap the stock air filters for K&N filters. I have always been pleased with the superior quality and performance of these filters. I have used them in everything from a Toyota Corolla to a Camaro SS. They are especially useful if you intend to install a higher flowing exhaust system, because the high flow cannot happen unless you remove some of the intake restriction.

I have been purchasing K&N products since 1995. I have yet to have a bad experience with any of their products. I would truely recommend K&N filters to anybody whom wish to get the most out of there vehicle's intake system. K&N is money well spent.

Excellent product... noticeable difference in performance as soon as it was installed... let's in so much more air that I had to have the ECM reprogrammed...
