The manual & dealer ship recommend 41-940 plugs, same as other 3.4's.
The plugs in my 2000 GAGT are 41-952. The ACDELCO site does not even list these plugs. Any suggestions?

I'd go with what the dealer recommends. GM upgraded the plugs to Iridium-tipped electrodes in 2003 (I think) from the platinum plugs that your car originally came with.
