What brand and how long are you planning on keeping them in there for ?
For me, Champion Iridiums and I will be keeping them in if all works out for 100,000 miles with the odd inspection here and there.

NGK's. I'll probably swap them at 30K.
I'm not using Iridium now, but I'm thinking of switching. The original stock plugs were completely eroded at about 35,000 miles on my 2005. I had replaced them with NGK V Powers.
GM Owners Manual cites AC Delco Iridium plugs as replacements. Not sure why regular delco's were in there????
