I know one of the guys was going to do some research on which of the Donaldson, Baldwin, Duralite etc type paper air filters would fit the '03 trucks, but haven't read anyone who's found one that'll fit. I rummaged thru the Donaldson site this evening, all the 4" inlet filters are too big for the hole. Had great performance on my '01 with one, but would need a BFH to get it into the '03. Anybody had any luck? How about a suitable alternative? Any suggestions appreciated, but forget the K&N, and like filters, I won't use them. TIA Ron
