[QUOTE="Pappy, post: 398244, member: 3278"] Mark Fisher got it right. The plug tip is what runs hotter. All else is the same. Cooling system has not changed. Air/fuel ratio has not changed. The hotter spark plug is simply not transferring that combustion chamber heat into the cylinder head/cooling jacket as quickly or efficiently as the correct plug will so the tip runs hotter than the original or a cooler plug. Following that a little farther you would think that a colder plug might warm an engine a little quicker since it transfers more heat into the cylinder head/cooling jacket faster. [/QUOTE]
