NOOOO...made that mistake already. Autolite 103 is like a stock plug
you want autolite RACING 103....that is like a tr-6...if you pay less than 10 bux for the autolites, you got the wrong plug. AR103 plugs are about 20 bux at advance auto

If you find sombody at parts store that knows what the hell the are doing like me 
in the back of the autolite book and most other brands, there is a heat range chart, all the plugs are group by thread pitch and reach, and then listed hottest to coldest
