a 103 is a step cooler of a heat range. Mainly a nitrous/ supercharger plug

a 764 is a copper core, and is a great plug...

Copper Cores work the best in these motors BTW. the 103 is a Copper COre too, but is a heat range cooler.

Persoanlly i have 764s in my car at the moment, but have a set of TR-6s going in in a week and half.

764 is the stock plug...

103 is a step cooler than a 764

AR94s are two steps cooler
AR93s are three steps cooler
and
AR92s are 4 steps cooler.
