I have been buying K&N filters for all my cars and trucks for 20yrs. I would never use any other filter. Thanks for a great product

I have used K&N products in the past with very very good satisfaction with my new SUV´S I looked to have them again.

I agree- definitely a noticeable increase in HP from the factory filter. Breathes a lot easier, accelerates better after the magic 3000 RPM mark on this engine, and even makes it sound tougher.
