Excellent. I've had K&N filters on all my cars. Just got one for my new F150. Keep up the good work.

I'm unable to accurately rate this item as I have just started using it in my vehicle so I cannot tell if there is any improvement over the OEM filter. I DO know that K&N filters are reportedly superior filters and that was why I chose to replace the stock filter with this K&N. I do like the lifetime longevity of the filter with a mild cleaning and re-oiling. Do not use compressed air to dry the filter as it will destroy the cotton gauze material.

This air filter fits easily into the stock Ford F 150 airbox. This will be the last filter you ever buy. I noticed I'm getting better gas mileage and a little better performance. This is a great product. I've had K&N filters in other cars and motorcycles.

Installation would have been a bit easier with some instructions. Had to pull up a video to get it done properly.
