a.. 3100 (VIN M) AC Type 41-940; 1.52 mm (0.060 in) Gap
thanks for the help, but can i put the platinum plugs in my car that didnt originally come with them from factory??
I don't think that you should leave plugs in there for 100k miles. Why not go with an aftermarket brand if you want the platinum?
