I've bought air filters for my last 3 trucks and seen no reason to stop. And also a air tube for my GMC. The vehicles run better with them.

No brainer. Don't need to think twice. Best filters on the market.
Paul Podosek, Suffield, Connecticut
I purchased this K&N Filter for better performance and increased MPG. It arrived in a timely manner and at a reasonable price. This is my second purchase of this type of filter for vehicles I own. The filter is an exact fit and easy to replace with less maintenance over the years.
