K&N online shopping is efficient and easy. The products are top of the line. I've used the air filters for over 15 years and enjoyed the incredible benefits of their cold air replacement intakes as well. A definite must for any car owner.

So far it's fine. Feels like it may have improved performance. I don't see why it would not. It was easy to install. Just a replacement but it looked better than the original. What do you estimate it adds HP wise?
Brad Lange, Wesley Chapel, Florida
No doubt this filter has changed the performance of my truck.
