No matter what car I drive (and I've own 6 so far), I will always have K&N in it... dependable and very long lasting, it out performs what you would expect from just a simple air filter.

Simply awesome. This filter gave my already high MPG a boost. Glad to be apart of the K&N way now.

Great product as always and I will always recommend your products. I like the fact that you can clean filter yourself and with little difficulty. Great filter and fast shipping. Thanks all at K&N!!!

3rd vehicle in a row for me that has been converted to K&N and no comparison... I think everyone should convert just for the sheer satisfaction of telling the dealer "NO thank you! I have a million mile filter" when then suggest a new overpriced filter.. hahaha..

Seems like a good product which is washable and reusable. I have not noticed any changes in my vehicles performance which is fine.
