Natalie, our 4.2 engine only likes 1 sparkplug. AC Delco 41-103. This Iridium plug comes pre-gapped, to near the specs Mike posted. Don't try and gap these particular plugs yourself, easy to ruin them.

You hear the air compressor turning on/off that inflates the rear air bags; the vehicle does a check when it's started, and will add air when you add weight to the cargo area or add a full load of passengers.
