I replaced the filter for hopefully a little better performance and mileage. I have them in everything from my work car to my motorcycle. It may just be my imagination, but I have used them for about fifteen years easy. They have a million mile guarantee and can go about 50,000 miles without cleaning. Plus, under the Magnuson Moss Warranty Act, it won't screw up your warranty.
