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.
Floyd Smith, San Bernardino Califormia
Have used several different K&N products in all my vehicles. Never failed to impress. Great product built locally. Try one. You won't be disappointed.
