I know that platinum plugs last longer but do they actually produce a HOTTER spark. Also, I bought a set of Autolite's that have the platinum electrode "without" the little platinum pad on the underside of the grounding tang......will they produce

Spark plugs are not for "producing heat." It's the spark that ignites the fuel, not heat. When heat ignites your fuel you will get pre-ignition and subsequent engine damage.

Before you spend a lot of money on plugs do some thorough
