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: KI6R-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

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

7. RECONNECT HIGH-TENSION CORDS TO SPARK PLUGS
