I buy a K&N filter every time I buy a new truck because they will last the life of the truck.
Conrad Milner, Hayward, California
I've been using K&N filters for years. This one really made a noticeable difference on my first drive with it installed. The engine revs easier, higher and has more torque.

Based on a long history of using K&N, I replaced my son's Toyota Tacoma air filter. It was very easy. I am less than a month on the new air filter so can't comment yet on how well it is working.
