Don't know if anyone brought this up yet but Tornado Alley Turbos has
recently issued an "mandatory" service bulletin on fine wire plugs.
Apparently they are more prone to insulator cracks than the massives.
When the insulation falls off they turn into "glow plugs" and can lead
to a detonation event. I think George has documented this. Here's the
SB:
