Plugs where purchased from Oriley but are the same PN as those sold at the dealer. NGK laser iridium (SIKR9A7). I will say that I have read all sorts of different gap specs anywhere from .020 to .027. Mine were at the high end out of the box.
Coil Packs 1 of them (#2) was replaced by the dealer when the multivalve work was done, the other 3 are the same mfg (BERU) and PN as the unit the dealer installed but come in a Duralast branded box (from autozone).
