Today was the the first day I used the K&N air filter in my 2003 Maxima SE. I use my cruise control option every day on my drive back and froth to work. Going home from work my MPG went from 26 that I would normally get from the stock air filter to 30-31 MPG and going to work 34 to 38 MPG with the K&N. This air filter gives an extra 90 to 95 MPG per full tank of gas. Today the way the gas prices are going this was a big help me and my family. Thanks K&N!

This is my 2nd vehicle now with a K&N air filter. This vehicle has noticeable more power on start from a stop and I have calculated a 3.1 MPG increase with no other maintenance performed on this vehicle. I received a recommendation for a K&N air filter from a friend and have also continued that practice with my friends and family. Great investment for any vehicle of any year.

The performance of the vehicle was markedly better after installing the air filer so much that I was truly amazed. The engine can breath a lot better and the gas mileage has improved. I really like the idea of just cleaning the filter instead of replaceing it every so often too. It's really a great product. Thank you so much, I am spreading the word.
