Tightening torque

Spark plug gap spark plug: 11 n·m (1.1 Kgf-m, 8.0 Lbf-ft)

  1. Remove the spark plugs. Refer to “ignition coil and spark plug removal and installation” in section 1h .
  2. Measure the spark plug gap using a wire gauge. If it is not within the specification, replace the spark plug.
Caution


  •  To prevent the damage of iridium center electrode, use a wire gauge to check the gap.
  •  Never adjust the spark plug gap.

Electrodes condition

  1. Remove the spark plugs. Refer to “ignition coil and spark plug removal and installation” in section 1h .
  2.  Check the worn or burnt condition of the electrodes.

    If it is extremely worn or burnt, replace the spark plug. And also replace the spark plug if it has a broken insulator, or damaged thread.

Caution


confirm the thread size and reach when replacing the plug. If the reach is too short, carbon will be deposited on the screw portion of the plug hole and engine damage may result.
  1. After finishing the spark plug inspection, reinstall the removed parts.
