My plugs at 114k (pic)
Just getting around to changing the plugs on my '02 FX4 with 114k miles on it. So far I've done plugs 3 and 4 (I'm taking my time, lol!). They both look the same. I'm pretty impressed how they look with this many miles. The gap on the pulled plug is .061 compared to the new one at .056. Not bad.

They show the following;
The beads is the additives in the gas formulation you use.
The tip is normal spark and high temp errosion.
The porcelean also shows some shoulder errosion as well as the ground strap..
Heat range is perfect.
All normal for a plug with that much use.
Good luck.
