Wondering about the platinum pucks on the AC Delco plats. I've seen threads where people have said that the platinum pucks have come off, even after relatively low miles being put on them. Does this happen only on the standard ac delco plat. plugs or does it also apply to the AC Delco Platinum Rapid fire plugs or Bosch Platinums as well? what are some sympthoms of the plat puck falling off? thanks.

 

I would also like to know the symptoms. I have the standard plats.
