Spark Plug: Testing and Inspection

IGNITION SYSTEM

ON-VEHICLE INSPECTION

INSPECT SPARK PLUGS
a. Disconnect the high-tension cords from the spark plugs. (See step 2)
b. Remove the ignition coils.




c. Using a 16 mm plug wrench, remove the 6 spark plugs from the RH and LH cylinder heads.




d. If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner.

Air pressure: Below 588 kPa (6 kg/Sq.cm, 85 psi)
Duration: 20 seconds or less

HINT: If there are traces of oil, remove it with gasoline before using the spark plug cleaner.




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

Recommended spark plug:
- DENSO made K16TR11
- NGK made BKR5EKB-11




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

Correct electrode gap: 1.1 mm (0.043 in.)

g. Using a 16 mm plug wrench, install the spark plug.

Torque: 18 Nm (180 kg.cm, 13 ft.lb)

h. Install the ignition coils.
i. Connect the high-tension cords. (See step 2)
