Spark Plug: Testing and Inspection

1. DISCONNECT HIGH-TENSION CORDS FROM SPARK PLUGS





2. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the 6 spark plug.





3. CLEAN SPARK PLUGS
Using a spark plug cleaner or wire brush, clean the spark plug.





4. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for electrode wear, threads damage and insulator damage.
If abnormal, replace the plugs.

Recommended spark plugs:
ND K16R-U
NGK BKR5EYA





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

Correct electrode gap: 0.8 mm (0.031 in.)

6. REINSTALL SPARK PLUGS

Torque: 20 N.m (200 kgf.cm, 14 ft.lbf)

7. RECONNECT HIGH-TENSION CORDS TO SPARK PLUGS
