Installation & Maintenance Guide

1. Preparation: Warm up the engine to operating temperature, then turn off the ignition. Allow the cylinder head to cool slightly if necessary.
2. Removal: Use a spark plug socket and ratchet to unscrew the old plug counter‑clockwise. Inspect the removed plug for wear or damage.
3. Gap Adjustment: If required, adjust the electrode gap using a feeler gauge to match the manufacturer’s specification (typically 0.7–0.8 mm).
4. Installation: Hand‑tighten the new NGK CR9E plug into the cylinder head, then use a torque wrench set to the recommended value (usually 13–15 Nm). Avoid over‑torquing.
5. Final Check: Verify that all plugs are seated correctly and that no gaps or misalignments exist. Reconnect the ignition system and start the engine to confirm smooth operation.
