Both NGK and AC Delco plugs were installed from the factory. I have seen one owner trucks that had never been serviced have 3 AC Delco plugs in one head and 3 NGK plugs in another.

Double Platinum plugs were the OEM plugs. The premium iridium plugs (iridium center electrode w/ platinum ground electrode) work nice in my experience with them.
