I'm looking to change my spark plugs and wires. When I search for AC Delco 41-985 it doesn't seem to exist in the AC Delco website and almost all online reputable sellers don't even carry it. Then I read it was changed to 41-110.
However, when I plug that part number in for my 2000 C5, it doesn't say it fits. So which part number should I be using?
Also, what's the PN for the GMPP performance red plugs? I don't want to order the wrong ones.

Id just throw a set of copper NGK TR55 plugs in. They are cheap and outstanding plugs. Very low misfire rate compared to the rest. GMPP wires or MSD are a good set of wires.
