Spark Plug: Testing and Inspection

SPARK PLUGS INSPECTION

1. DISCONNECT HIGH-TENSION CORDS FROM SPARK PLUGS





2. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the 4 spark plugs.





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, thread damage and insulator damage.
If abnormal, replace the spark plug.

Recommended spark plug:
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. INSTALL SPARK PLUGS
Using a 16 mm plug wrench, install the 4 spark plugs.

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

7. RECONNECT HIGH-TENSION CORDS TO SPARK PLUGS
