Spark plug heat ranges chart
May 6, 2020 · A spark plug's heat range indicates how much heat the plug is able to remove from the combustion chamber. That seems a little counterintuitive, as you may think that it would refer to the amount of heat generated by the plug on ignition, but no. Spark plugs run at a temperature of 500 to 850 degrees at the tip. A good rule of thumb: use one heat range colder for every 75–100hp added. In identical spark plug types, the difference from one full heat range to the next is the ability to remove 70°C to 100°C from the combustion chamber. The heat range numbering system used by spark plug manufacturers is not universal.

ACCEL HP Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. A cold heat-range spark plug (left) can be identified by its rather shallow depth between the porcelain and the spark-plug body. A hotter plug (right) creates a much longer heat path to the plug shell that raises its operation temperature. Photo: Jeff Smith.…
