Thats really funny, you just repeated what I said. I raced dirt track in southern PA as well as drag raced. I'm older than you, I turned 57 last week. I don't have an agenda, I just smile when people say what you have said about something "WORKING" . I think you're smart enough to know that "oil additives" don't make horsepower and as you said neither do filters. If you like K&N filters and they cost the same, have at it, I only want people to know the truth.
