[Midwestern4x4]

Had a friend of mine tell me about this site some time ago. Finally got myself a 99 F250 7.3 , Has a K&N Intake , and Looks like 4" Straight Pipe no cat or muffler.

He keeps mentioning the K&N being bad but I can't find any reason why. I have tried to find stuff around here but K&N is a crappy search parameter.
Happy to finally be running a diesel..

Here is a few pictures
