Cracked insulator? This was a problem in the past. Mobis Plugs weren’t up to snuff.
 
Got the full 'life' out of my first set, they were changed at the scheduled service interval 70 thou I think, can't remember but it was a ~$700 service through the dealer
My misfire issue was put down to a faulty injector in the end.
