I did the plugs yesterday finally. I'm almost done I maintenance items. I've treated it like its never been serviced ever so it been a lot of work. I guessing these were the origanal plugs that came with the Jeep. I was pretty happy with their condition. None of them had oil or real bad carbon build up and all of them were wore out pretty even at .050 gap.





I still have the throttle body and stuff to clean and change the PCV. It looks like it might be pretty gunked up in their I'm almost afraid to look. Might just order a new one LOL
