Spark Plug Heat Range

Heat range is the measure of how fast the spark plug tip dissipates combustion heat. It must do this in a precise and controlled manner so the spark plug will:

  • Stay cool enough to avoid pre-ingniton and/or electrode destruction due to detonation.
  • Run hot enough to burn off combustion deposits that would otherwise collect on the insulator tip and cause fouling that results in misfire.
  • Adapt to specific engine characteristics and widely varying driving/load conditions.
