It does what its supposed to do. Gas mileage has improved and it has made accelerating more responsive. I've put K&N filters in all my vehicles and I've never been unsatisfied with the outcome. Thanks K&N. 1999 Chevy Cavalier 2.2l. 204,000 miles and still going strong
Timothy Hall, La Mirada, California
I have used K&N air filters in five different vehicles over the years and have been very pleased by the improvement in performance and increased gas mileage. Sometime in the future I plan to replace the K&N air filter on my '09 Camry with a K&N cold air intake system. That just sounds like fun. A great product

Excellent quality here! Quite a noticeable improvement over the stock air filter I had previously. Happy with the product!
