This filter installed very easy on my 2001 dodge 1500 quad cab truck with a 360 magnum. I noticed the power difference right away and my gas mileage also improved. Would highly recommend this upgrade to anyone.

Filter made a positive improvement, my old air filter did not look dirty either.

Excellent product. The filter fit better than the OEM one. Noticed a bump up in acceleration after driving for a few days. Way better than other filter brands. Money well spent.

I first remember using K&N filters in the 1970's on my dirt dikes, used them for years. Started using them in my truck in the 1980's. We have used them since. The first thing I do when we purchase a new vehicle is install a K&N Filter. I just bought a 2013 Ram, it has a K&N. My wife's Jeep has one. My daughters Truck has one. We are customers for life. Great products. Enough said!!!

This is my first K&N product. Drove the truck after installation and noticed the hp difference right away. After a few long distance trips I also noticed increase of mpg. It's winter so I drive in 4x4 right now. Big difference. Can't wait til summer to drive 2x to see the increase of mpg.
