SPARK PLUGS

1) Remove air intake pipe and cylinder head upper cover.
2) Pull out high-tension cords by gripping their caps and then
remove ignition coil assemblies referring to IGNITION COIL
ASSEMBLY in this section.
3) Remove spark plugs.
4) Inspect them for:
• Electrode wear
• Carbon deposits
• Insulator damage
5) If any abnormality is found, adjust air gap, clean with spark
plug cleaner or replace them with specified new plugs.
For iridium/platinum spark plugs, replace them with new
plugs.
Spark plug air gap
"a" : 1.0 - 1.1 mm (0.040 - 0.043 in.)
Spark plug type
NGK : BKR6E-11, IFR5E11
DENSO : K20PR-U11
NOTE:
NGK IFR5E11 is highly recommended for better engine
starting performance under -25°C(-13°F).
CAUTION:
• When servicing the iridium/platinum spark plugs (slen-
der center electrode type plugs), do not touch the cen-
ter electrode to avoid damage to it. The electrode is not
strong enough against mechanical force as it is slen-
der and its material is not mechanically tough
• Do not clean or adjust gap for the iridium/platinum
spark plugs.
