Air Filter Help!!!!

[bigjb08]

Alright guys! Another dumb question is coming your way. 2001 PSD, and before I heard all the bad things I had a K&N. After reading alot of peoples post out went that ole thing. Now I am running a regular wix filter. No problems, just want to know what you guys think I should run in this thing.

Are you running the big 6637 filter. Or the OEM replacement filter.

I'm using a Baldwin that is the same as the 6637. Last night I ordered a tapered open cone type filter made by Donaldson. My theory is that the if filter is crammed in between the battery and the fuse box, the fender and the hood insulation, it has to be restricting the air flow. I am going to try a smaller diameter cone shaped filter with a hollow end for more surface area. This and the Zoodad ought to be an improvement. Hope so anyway. I installed a chip in the truck this past weekend and it is screaming for more air!

Just a replacement wix air filter is all it is.

i had a k&n and i hated the noise. so i got the for a.i.s. kit from the dealer for $220. it has the same or more flow than the k&n. it looks like the same filter as a 6.0l. plus there is no air intake noise and the turbo whistle is as loud as the k&n and i know the filtration is at its best. also did the zoodad. i have no regreats about my purchase. hope this helps.
