Video Transcript

Why there are different heat ranges? It is a misconception that spark plugs create heat, this is not true. A function of the spark plug is a channel heat away from the tip of the spark plug. The length of the insulator mass determines the speed at which this is done.

A spark plug with a longer insulator mass is considered a hot heat range while shorter insulator mass is considered a cool type heat range. Selecting the correct spark plug heat range will ensure that the spark plug will reach a high enough temperature to keep the insulator mass clean. Too warm of a heat range can lead to pre-ignition or engine knocking. Too cool of a heat range can result in fuel or carbon fouling.
