Spark Plug: Testing and Inspection

SPARK PLUGS INSPECTION

1. REMOVE HIGH-TENSION CORDS AND IGNITION COILS





2. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the 6 spark plugs from the RH and LH cylinder heads.





3. CLEAN SPARK PLUGS
If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner.

Air pressure:
Below 688 kPa (6 kgf/cm square, 85 psi)
Duration: 20 seconds or less

HINT: If there are traces of oil, remove it with gasoline before using the spark plug cleaner.





4. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for thread damage and insulator damage.
If abnormal, replace the spark plug.

Recommended spark plug:
ND: K16TR11
NGK: BKR5EKB-11





5. ADJUST ELECTRODE GAP
Carefully bend the outer electrode to obtain the correct electrode gap.

Correct electrode gap: 1.1 mm (0.043 in.)

6. REINSTALL SPARK PLUGS

Torque: 18 N.m (180 kgf.cm, 13 ft.lbf)

7. REINSTALL IGNITION COILS AND HIGH-TENSION CORDS
