Does anyone know the part number for AC-Delco Iridium plugs for my 07 Silverado CC 5.3 all aluminum engine?

Napa, Parts store of your choice.

I believe its 41-985

Yup NAPA Parts guy here... I would definitely second the 41-985 AC Delco's (but it is currently being phased out and replaced by the 41-110). But be prepared I just might have had NGK's from the factory....... If it does the 41-110 or 41-985 is the AC Delco replacement. Both the 41-985 and the 41-110 are iridium plugs. My NAPA Store still has mounds of 41-985's on the shelf and plenty of 41-110's
