I would either run the NGK or the bosch plugs. I think that they give a little better spark then ac delco

 

Delcos are black oxide'd, so they're black, and hard to read. I like Champion (I think), because they are silver. Do you know much about the engine? Might want to check what heat range the plugs are that you remove, and see if they were the right heat range first. (in case you weren't thinking of doing that already...)

 

i recommend Delcos, the only plug you'll ever find in any of my GMs.
