I got my K&N air filter around 4 days after I ordered it. It was definitely cheaper than the local Auto parts store! I think I can feel a slight bump in acceleration but I haven't checked my gas mileage yet. I'm sure it's better. I love the filter! It fit right in no sweat. I can tell it gave it a little more air flow.

Love this filter! It gives the car a nicer sound and a little better performance. I have these filters on all my cars.

Easy to install. I would recommend a K & N Filter to anyone. I have the K & N cold air kit installed on my 2004 Chev Silverado 2500 HD.
