Cold Air Intake

The stock air filter on the 6.0 powerstroke is actually an outstanding filter. The honey comb design traps dirt great and allows air to flow excellently. It is my recommendation that you do not do anything with it. If you must change it though just because you want to DO NOT use K&N. K&N will cause you much hassle, and they are very prone to dusting turbos which will cost you a good bit in repairs. People not cleaning them as often as the should has a little to do with that. K&Ns are also just a pain to deal with as far as getting them on and off. If you really want a cold air intake I recommend S&B. It is a great filter along with the fact that they have the housing around them. Do not cost yourself money in repairs that is unnecessary.
