OK, the OEM plug is GM part no. 12556183, a repackaged NGK PTR5C-13. Gap is .050. Torque is 15 ft-lbs. Anyone who tells you different is mistaken.
I used whatever the Zone sold me, some NGKs.
Factory mentions nothing about dielectric and I wouldn't use it.
Install boots onto coil pack then coil pack onto cylinder head cover.
