I have used K&N style performance air filters on all of my vehicles for over a decade now. I have not once had any problems. They flow better but they filter better too; they're just a better design. I know guys with over 300k miles on their Powerstrokes running [similar] performance systems and they see PLENTY of off road conditions - WAY, WAY more than my 300D ever will. But unfortunately as vstech pointed out, something should be done to get colder air directly to it. With that stock mess removed I had plenty of room to mount my veg oil filter system; no way I could have put it in there with that in the way.
