The K&N filter provides much more air. I am using this filter on a diesel with a turbo. There is better throttle response, turbo spools quicker, EGT is lower. Should help mileage if I can keep my foot out of it. This is my third vehicle I have used a K&N on, they are well worth the money.

This time I like sucking wind.
