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 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, 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 spark plug.

Torque: 17.6 N.m (180 kgf.cm, 13 ft.lbf)

7. RECONNECT HIGH-TENSION CORDS TO SPARK PLUGS
