I've been using K&N filters for many year in my motorcycles and vehicles. They have alway performed outstanding.

It's too bad this filter is covered by the factory air box because it's a thing of beauty. The instructions were simple and easy to follow, though it would have been nice to have a few helpful hints to getting the OEM filter box out. Fit & finish is excellent with a tight seal as it should be. My fuel mileage immediately jumped up by 3 to 4 miles per gallon, but I'm sure some of that had to do with the dirty restrictive OEM filter element I removed.
