The filter works great. My gas mileage has picked up about 5 more miles to the gallon.

Purchased this K&N air filter for my daughters car that we purchased for her. Did so to avoid her from ever having to buy an air filter for it. Have K&N air filters on 86 Porsche 944, 99 Chrysler 300 & 2007 Saturn Outlook XR. That says it all.

Bought it for my 2005 Chevy Cobalt. Easy installment. No problems.
