I know this seems obvious, but please bear with me. The owners manual for my 05 V recommends OF # 25010633 (AC Delco PF44). The online GM supplier says to use 88984215/PF46. Is he wrong or have the numbers been updated? Thanks!

A PF46 works. A Wix 51042 is a better filter. The best filters are Amsoil.

when all else fails, and you don't read the FAQ... and they both obviously fit.... bigger is better!

FYI - Those will NOT fit an '07. The thread size changed for '07.
Brian, when you say, "those," are you referring to everything in the whole FAQ chart?

Heck, what do I care?!! I've got an '05! :highfive:
