Spark Plug: Service Precautions

NOTE: This engine is equipped with an aluminum cylinder head. Allow the engine to cool before removing spark plugs. Removing the spark plugs from an engine at operating temperature may damage the spark plug threads in the cylinder head. Also be sure to clean any dirt or debris from around spark plug holes prior to removing spark plugs.

IMPORTANT: Note the correct routing of the wires prior to removal in order to maintain the correct engine firing order.
