spark plug torque 2007 L76
Ya just snug them and make sure to use anti-seize on the threads, the actual torque is 11 ft-lbs. Doesn't really matter if the engine is hot or cold, cold would be better so you don't burn yourself on the engine.
Seven or eight pounds foot torque is all that's needed lots of people have backed out their plugs with the alum threads attached.
This is because the conic seal leverage the threads hard notice is hard to brake the spark plug loose.

Here's a decent thread on this topic.

I use a torque wrench and do all eight plugs to 11 ft/lb per GM spec. No issues on the 99TA and it's had like a dozen plug changes over ~163,xxx miles. A little anti-seize helps too.
Many people have no idea what 11 ft / lb of torque feels like on a plug. I suggest tightening a couple of the easy to reach plugs with the torque wrench to get an idea of the correct snug feel. It's easy to over tighten plugs in an aluminum cylinder head.

Spark Plug Removal Hi, MY PROBLEM was different, the removal of the Spark Plug.
The case was my 2007 L-92 Escalade.
They were so tight I thought the head would strip, pull the threads.
I "soaked" the plugs in WD-40, this allowed removal.
WHAT WAS FOUND : NO Anti-Sieze, NO lube of any kind. (OEM Assembly)
I USE Copper Slip (jet nut) on ALL my plug installations.
This IS best for heat transfer.
I USE Silicon Grease on the SP Boot.
Yes, the boots too were "damaged" upon removal at first change, they too were frozen onto the insulator.

Just make sure you don't goop the anti-seize on there because you will get misfires. I seen it happen to a friend. Cleaned off threads and misfire went away.
