01 Suburban plug help needed

I have a 2001 Suburban 4x4 with 8.1 ltr. engine and I have not been able to find any ACDELCO iridium plugs listed for this truck. Does anyone know if they make one that will work well, or do I need to stay with the Platinum? I do not want to use any other brand.

Wow. the 8.1L. Sweet. Always wanted to see one...

As for the plugs
I cant find AC Declo's either but. I dont see why these wouldn't work:
BOSCH Part # 9612

I had to go under 2500 Suburban and then pick the 8.1L. Couldn't find a thing under 1500 8.1L.

Since these vehicles do not play well with aftermarket spark plugs, I would recommend sticking with the OEM AC plug. If that is a platinum plug, I would use that.

Rock Auto States Iridium are the OEM. But no acdelco. I would go with the Bosch plugs. They are the same gap. Same material. I now its a different brand. But very close plug.
