Rock Auto has the Delcos, with a rebate.

I can't find the Iridium plugs. I did find the Delphi wires on their site.
What's the plug #? is it 4110?

41-110 is what I remember it being. :dunno:
The wires aren't a biggy. I just put Delphi's on the last time because that was OE on the truck.
My truck takes the same plug and it shows up there.
Where? :dunno:
I just found some on ebay. :lol:
On Rock Auto, go to '08 and look. That's where I found them. I have a 5.3 but it takes the same plug.
OK...thanks! :thumbs:

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:

I would say it's a safe bet that they are made by the same company...:lol:

On your original question.... NGK is a good choice since they are known to produce AC D plugs, but I've also used Denso in place of AC D with zero issues

I've wondered if they dropped the iridium recommendation for older vehicles, figuring they have higher mileage, maybe using oil, the platinum plugs would last plenty long under these conditions

Half way between here and there.

That would make sense. I have ran regular NGK plugs in mine for 60k miles with no issues. The only reason to run the iridiums is not having to change them in 100k miles.

I've never given that a thought, but definitely makes a lot of sense. :thumbs:
