Some of you probably saw my broken plug, well here it is in all its glory with the rest of em'. Waddya think, been in there for 100k+ miles? The gap is better than .090. Crazy as it is the jeep was running pretty well.
LJ were you a marine? Ha, sounds like something they would say, ha.re-gap 'em, jb weld 'em and put 'em back in
Looks familiar, I pulled these out of mine shortly after I bought it. 200K miles no idea when they were last changed. Oddly I thought it ran fine!

What year is your Jeep OP? Coil-on-plug systems can get rowdy on spark plugs. On my old 4.7 WJ I replaced the plugs shortly after buying it at 100k and there was literally no electrode left sticking up on any of the plugs and it ran fine enough to not notice beforehand.
