Works great like my previous K&N products.
Ojay Lewis, Connecticut
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!

I purchased this for my 2006 Subaru Forester 2.5X. Installation was simple, and with the first tank of gas, my gas mileage increased by 2 MPG. It even sounds stronger. The Forester has 130,000 miles and is a 5 speed manual.

Passgenauigkeit und verarbeitung sehr gut.
Paul Robson, Elgin, United Kingdom
Brilliant product. Does everything it says on the box and is better than having a cone squeezed into the models engine bay. This product fits in smooth and fast it only takes a few bolts and your done its so simple .And it makes it sound more of a machine than a pussy cat.

Delivery was quick, can't fault the product. If you need a new filter why not get one that will last and preform better.
