Power and mileage went up, couldn't have asked for more.

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
