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. 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: KI6R-U
NGK: BKR5EYA

4. ADJUST ELECTRODE GAP.



Carefully bend the outer electrode to obtain the correct electrode gap.

Correct electrode gap: 0.8 mm (0.031 in.)

5. CLEAN SPARK PLUGS



Using a spark plug cleaner or wire brush, clean the spark plug.

6. REINSTALL SPARK PLUGS.
Torque: 18 Nm (180 kg.cm, 13 ft.lb)]

7. RECONNECT HIGH-TENSION CORDS TO SPARK PLUGS.
