Just a tid bit. I am a service manger at a repair facility, most hemis are using a copper regular resistor plug. Champion rc14mcc4. That plugged is rated from the manufacturer to only last 30k. Also if you have a warranty issue that is to be covered under your factory provisions you have to be able to provide proof of plugs being changed every 30. I do agree when I pulled my plugs at 30 and 60 they looked new but for $32.00 for the parts and about 2 hours, I think its justified to do every 30.
