simple task of replacing spark plugs on the I5
I replaced plugs today on my truck with the I5 and was relived on how simple GM made it to replace them. seemed odd someone was there before and replaced only one coil pack and left the other four alone and the plugs were wore about the same with only about .046 max on the plugs. I read online to gap them at .042. replaced them with new AC Delco.
