Look at the post date bud. 12-22-2003, 02:34 PM That was a loooooooooong time ago. Live and learn.

Sorry

Did you get rid of the k&n? If yes, may I ask you why? Did you experience any problems or was it from readings on how inefficient they're at preventing dirt from entering the engine?

Did you see any difference going back after the k&n?

Went back very quickly. My engine ran like cr@p with it. Mostly it was too small but I was very glad to get rid of it once I started researching them.
