I think in 2003 GM went to the PF44 (short version) for standard on trucks too and not the PF59 (long version) of the previous years. No matter on all of the LS style engines the WIX 51522 or NAPA Gold 1522 (identical filters made by DANA) is the right filter for this engine. Don't use NAPA Silver though !!!

I got a Chevy 2003 2500HD with a 6.0L. Looking at using a Wix filter and Mobil 1 oil. Anyone have any thoughts?
