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.

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.
