You'll want to go with the Iridium NGK LTR7IX-11 (stock #6510) plugs. They're on Amazon, but you can find them a bit cheaper at Rock Auto:

In the interest of full disclosure, opinions will vary, and you may want to gap them at .035" to cut down on misfires:

does it set a code? both stock gen6 Camaros I have been in seem like they have a random miss when cold. If there isn't a code I think it is normal.

FYI. I'm seeing a lot of resources that recommend closing the gap to .030 to help smooth out rough idles. I think that's worth a try. .030 is definitely recommended for a forced induction setup like mine, and I'll be installing these plugs with a .030 gap tomorrow.

Just got the car back. The idle is very smooth from a cold start, and I did some spirited driving. No issues at all with the .03 gap.

Open the gap to 0.042 and the misfires will go away.

If your tune up is right it will be no problem at this power level.
