Changed out the factory spark plugs and wires today on my 04 Yukon SLT. Took out NGK factory plugs, also stamped AC Delco and replaced them with the factory AC iridiums. Also replaced the wires with the AC factory wires. Pretty straight forward, gapped them to .040, little antiseize on the plug threads, and dielectric grease on the wire ends. It is my wife's driver and her, her mom and my daughter on going from NJ to MO next week, so I am checking it out and getting stuff done on it now. New O2 sensors go in tonight since I have 1 bad one, just replacing all 4 to be done with it. Got everything from Summit Racing and got it quickly at that. Just confirming what others have posted in this forum regarding the plugs, wires, difficulty, etc. I am also ASE certified so that kinda helps, LOL. Very easy so for you guys contemplating doing it yourself, I say grab the parts and have at it. If anyone wants part numbers, I'll post them if asked.
