AC Delco's site doesn't list tose plugs for your truck. But what plugs it shows for yours are the same for mine....:dunno:
I know. They switched them from the iridium's to platinum's which makes no fWONking sense. I've never ran anything but AC plugs in my trucks and I have no intention of switching now. You know come to think of it...when I changed the original plugs out about 80K ago, they had AC Delco printed on one side and NGK on the other. :confused:

On my 2001 Suburban, I do remember when I first replaced my original factory spark plugs at about 70k miles or so, they were actually NGK plugs. I also remember reading somewhere that the AC Delco 41-110s were actually made by NGK. Last time I replaced my plugs, I didn't see the AC Delco iridiums listed on Rockauto so I ordered a set of NGK Iridium plugs. And for plug wires I am running a set of Belden plug wires from Napa, bought those around 2010 or so. They have a lifetime warranty, so I can just go swap em out whenever I need new ones. :dunno:
