The term spark plug heat range refers to the speed with which the plug can transfer heat from the combustion chamber to the engine cylinder head, it has been found the optimum combustion chamber temperature for petrol engines is between 500 degrees C – 850 degrees C when it is within this range it is cool enough to avoid pre-ignition and plug tip overheating which can cause engine damage, while still being hot enough to burn off combustion deposits which cause fouling.
