Thread: k&N filter yes or no?

I have considered giving these a whirl. They seem to be pretty popular in the diesel world. Has anyone used one on their GP in stock configuration or with a HAI or CAI?

AMSOIL AMSOIL Ea Air Filters

I see it both ways..... stock airbox is fine and not going to hurt your power in most sub 350 crank horsepower setups..... but at the same time a cone filter releases the manly as **** orgasm inducing scream of the m90..... as far as filtering goes a k&n lets more dirt in but millions upon millions of miles worth of drive time has been done by people without a single one blaming a k&n for a dead motor.
