I have used K&N filters on others I have had and always been happy with the performance of them.

K&N are the only filters I use. It improved the performance of my Surban back in 1990 and have used it on every car since. Thanks it a great product. Phil

Been using K&N's since 1971 in my racing motorcycles. When they started making car air filters, I IMMEDIATELY installed one in the Dodge Maxivan I had then, and in ALL my vehicles ever since then, to this day. For me it's the only way to go. They do the job in the worst/dusty conditions, and last forever. I Haven't bought a paper filter for any car since day 1.
