Thanks for the information, does this plug have the platt that either burms off or falls off?? As I am NOT using a duel platium style plug this time. I have read on the Corvette Forum that several other brands of this type of plugs have the same problem.I pulled all of the plugs and 5 out of 8 were missing the platt (disc) on the ground where you gap the plug at. I hope they did not scratch the cylinder wall.
