Do you need to replace spark plugs on Acadia?

How do you install new spark plugs on GMC?
I put a little anti-sieze on the threads and a dab of dielectric grease on the coil pack boots before installing the new plugs. All of them had correct gap right out of the box. I spun the plugs in by hand, using only the extension, to avoid cross-threading.

What kind of spark plugs do GMC Delco use?
Also, if you use the AC Delco iridium plugs, they’re made by NGK, which already has a plating on them so they don’t stick in the head. The GM manual does not state to use anti-seize, and neither does NGK. The originals I took out did not have anti-seize and they came out easily.
