Using a spark plug with an improper heat range can cause?

Spark plug heat range controls how quickly the plug sheds heat to the cylinder head, which sets the electrode’s operating temperature. If the plug is too cold for the engine’s operating conditions, it won’t get hot enough to burn off carbon or oil deposits, leading to fouling. If the plug is too hot, it runs hotter than normal, which can cause overheating, pre-ignition, or detonation. The right heat range keeps the tip in its optimal, self-cleaning zone. So an improper heat range can indeed cause fouling or overheating depending on which range is used.
