Hello, the gap is .060 i hope this info helps you out

  • Ensure that the spark plug washer is positioned correctly.
  • Inspect the spark plug gap. Adjust the gap as needed.

    Specification
    Spark plug gap: 1.524 mm (0.060 in)

    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.

  • Hand start the spark plug into the corresponding cylinder.
  • Tighten the spark plug.

    Tighten

    For used heads, tighten the plug to 15 N·m (11 lb ft).
    For new aluminum heads, tighten the plug to 20 N·m (15 lb ft).
    For new iron heads, tighten the plug to 30 N·m (22 lb ft).
