Spark Plug Heat Range
In identical spark plug types, the difference from one heat range to the next is the ability to remove approximately 70°C to 100°C from the spark plug center electrode and ceramic tip.
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.
