Just did plugs and wires for the first time at 100k miles. Is this wear on the #3 plug indicative of anything?

All 6 plugs out as pulled from engine

i have a 2007 with 150k and mine looked way way worse than that and it still ran fine. I would say you got nothing to worry about. Put new plugs and wires in and it is running like a top. 3.8's arent as bad as people think

It looks normal to me for a plug that has 100k miles.
