If installing a new spark plug, tighten l/2 turn after the spark plug
seats to compress the washer. If reinstalling a used spark plug, tighten l/8
to l/4 turn after the spark plug seats.

which have an improper reach or heat range may cause engine damage.
l The spark plug must be securely tightened. An improperly tightened
spark plug can become very hot and may damage the engine.
