  • Q:

    What does the heat range spec of D12 mean for the Autolite 63 spark plug? I'm not familiar with a heat range starting with a letter. Is it a heat range of 12? What does the D indicate?

      I'd be happy to help you with that! Every manufacturer specifies the heat range rating however they prefer. There is not a standardized measurement system in place for the plug heat range unfortunately. I located a heat range chart from Autolite using Google. The letter signifies the type of plug it is; in this case 'D' is a power tip plug. This plug looks to be a mid temp plug. If you Google "autolite heat range" you will find the heat range chart as well as a conversion chart from other brand's heat ranges to Autolite's.
