K&N 33-2465 Air Filter Product Reviews

I have been using K&N filters for years in every car I have ever owned ever since I found out about how good the filters were. I use them in all my street rods and my daily drivers. When I first got the filter in the 80's I washed them to often and was talking to a salesman from K&N ordering the cleaning equipment and told him what I was doing. He told me to stop cleaning the filter so often and just wait awhile. Now I know better and rely on K&N.
