Phillip Schneider, Bellbrook, Ohio
Very easy to install.
Geoff Henry, San Diego, California
Filter seems to be of good quality. Like the reusable aspect. Works well and I believe is providing an additional 1-2 MPG's since installation. Best of all was the price and delivery speed as the dealership wanted to charge $100 for one of the factory paper filters that have to be thrown away.
Paul Benschine, Madera, California
More performance, horsepower and better shifting.
