Installation Procedure






Note: The spark plug comes pre-gapped. Do not change the spark plug gap from 1.01 mm (0.040 in).

1. Inspect the spark plug gap. Adjust the gap as needed. Refer to Ignition System Specifications .
2. Hand start the spark plug in the corresponding cylinder.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Tighten the spark plug.

Tighten
- For used heads, tighten the plug to 15 Nm (11 lb ft).
- For NEW heads, tighten the plug to 20 Nm (15 lb ft).
