You could immediately tell the difference.<br /> Money well spent.
Matthew Jung, Vail, Arizona
The car has over 200K miles and I think this might be the final air filter. After 50K on this air filter, I am going to wash it and sell it on eBay, so I won’t have to deal with the messy oil and I will buy a new car. There does appear to be a little more performance above 3000 RPM, but I don’t notice any change in mileage.
Steven, San Diego, California
Increased power overall, especially improved low- to mid-range torque, and improved gas mileage.
