These are awesome filters. I have one on everything I drive.

Absolute best quality and durability/performance, hands down.

K & N purchase, The customer service department responded quickly to my emails, but I am not happy with the outcome of my issue. I will reconsider using Auto Anything again.

This is the third K&N filter I've used on my cars in the last three years (an Altima and a BMW X5). As in the previous cars, I have noticed smoother engine performance vs. a clean paper filter. Not a big difference in mpg- maybe 1/2 mpg, but every little bit helps.

Good deal!

You can notice the power right a way, also gas saving.

Glad I installed the K&N over the OEMs. Noticed a nice whooomp sound upon accelerating.

I have K&N filters in three diiferent vehicles including a motorcycle and I' fairly happy. The only one I really have issues with is the one I installed in my Ford F350 deisel. After driving up along incline while being moderately on the throttle the engine makes a strange sound. It does seem to do a good job though.
