K&N cold air intake?

I was thinking about putting in a K&N performance intake. Would this really make a difference in the way my diesel performs. I had a 93 F250 non-turbo and did just the air filter and noticed no difference. I also like to play in the mud would this be a bad move? Open to all suggestions.

Don't bother with the K&N. It's trouble on our DIT PSDs. Some folks run it, but a lot of people have problems with it letting a lot of dirt through. This is with either the drop-in or cone style filter. I run an open element 6637 filter, but I think you would benefit from the Ford AIS -- it's a much better filter than stock, doesn't leak, flows more, and won't get mudded up under the hood. You can see it here:

As far as the cold air part, it will be pulling in from the front anyway -- the Zoodad mod may help. But I would think attaching it to the fender might cause you to get too much mud/water in the filter. I have no experience with that, so maybe someone else with it will chime in.

I had the k&n kit on my truck when I bought it and after three months replaced it with the 6637 filter. The k&n definately dusted the inside of the intake tube while it was on there so I can only imagine what was getting through it. The 6637 has not dusted my intake tube at all in the same three month span, driving on dusty country roads. just for comparison, I cleaned the intake tube after I first got on this forum, so I know it wasn't an accumulation from before. I am not a rookie to k&n's, as I have had them on my 5.0 mustangs and other pick- ups that I have had in the past. On the intake tubes of the mustangs, I never noticed the dusting effect as on the diesel. the diesel is pulling so many more cfm though. Go with the 6637 mod and you will definately like it (it's cheap to do as well).
