I've alway's been strictly AC-Delco, but it appears those are not what comes in the 6.0. They either list Denso, or NGK. Why no AC-Delco's in these engines?

if the plugs that are in it are not AC Delco...someone has changed them.
It came with AC DELCO.
I was looking in the owners manual, and it doesn't show AC Delco as a replacement.
It just list's NGK or Denso.
One would think that AC Delco would be installed since it would be the lesser expense of the others.
I never had any issues with NGK, matter of fact I get them from AMSOIL. It is a product like along with Mothers that AMSOIL carries as well as Trico wipers.
Bet ya'll didn't know that!

I've got the AC Delco Iridium in my 6.0 (and the 4.8), which with only 25k, I'm assuming are the original plugs.

Yeah, I saw those were available at Advance Auto Parts, and Autozone. I just couldn't figure out why they were not in the owners manual. I've never used anything but AC's in my Chevy's.
