Roger Kruse, Toledo, Ohio
Tried a K&N filter in my 2003 Chevy Tahoe. I put it in and left Toledo Ohio headed for Apalachicola Florida. I was getting 11-12mpg around Toledo to an 18 Mpg on the trip. Boy was I surprised.

Bought this then found it a lot cheaper online called K&N about this they said just ship it back, pretty bad when you can get it cheaper from somebody else, but is a good product just won't do business with maker.

I have had this brand before and it worked amazing, so I purchased it directly from manufacture this time. It continues to work awesome in my 2007 Silverado and 2010 Tahoe.

Tim Lowell, California
I have K&N air filters in all of my vehicles. Just bought a GMC Sierra 2500 hHD. Put the K&N in before the odometer turned 1000 miles. The filters are just that good.
