Charles Cannon, Granbury, Texas
I have been replacing original filters in my cars since 1998, which is 7 vehicles. The latest is a Mercedes chassis 25 ft motorhome, which I have been pleased with and will continue to use K&N filters. This was my 1st purchase from your warehouse and was very pleased with the results. Keep up the geat job.

After your representative explained where to mount the air filter, it fit perfectly and am looking forward to it's performance.

The Filter is great! It was dented in one corner, but I was able to get it to fit the opening. Shipping I guess. My gas mileage has improved. I would buy again, thanks.
