SPARK PLUG

Removal and Installation


REMOVAL

1.Remove engine room cover. Refer to "Removal and Installation" Removal And Installation.
2.Remove the ignition coil. Refer to "Removal and Installation" Removal And Installation.
3.Remove the spark plug with a suitable tool.





(a): 14 mm (0.55 in)

INSPECTION AFTER REMOVAL

Visually check the electrode for dirt and wear and the insulator for burning.






(A) : Iridium alloy
(B) : Platinum alloy






- Do not use a wire brush for cleaning the spark plugs. Replace as necessary.
- If plug is covered with carbon, a spark plug cleaner may be used.

Cleaner air pressure: less than 588 kPa (6 kg/cm2, 85 psi)
Cleaning time: less than 20 seconds





- Checking and adjusting plug gap is not required between change intervals. If the gap is out of specification, replace the spark plug.

CAUTION:
Do not drop or shock plug.

INSTALLATION

Installation is in the reverse order of removal.






CAUTION:
Always tighten the spark plug to specified torque to align the orientation of electrodes. The ground electrode of a genuine spark plug is positioned in the area of maximum ignitability by tightening to the specified torque. When replacing spark plugs, use genuine spark plugs of which the ground electrode is adjusted.
NOTE:
The ground electrode of the spark plug is positioned in the area of maximum ignitability to improve combustion efficiency in the cylinder, reduce CO2 (carbon dioxide) emission and improve fuel economy.
