Installation Notes
- Ensure the engine is cool before starting work.

- Clean the area around the spark plug to prevent debris from falling into the cylinder.
- Using a spark plug socket, turn the old plug counter-clockwise to remove it.
- Check the gap of the new spark plug and adjust if necessary to match your engine's specification (1.1 mm is standard for this plug).
- Thread the new spark plug in by hand to avoid cross-threading.
- Tighten the plug with the socket until it is snug, then give it a final quarter-turn. Do not over-tighten.
- Reconnect the spark plug wire boot securely.
