Spark Plug Inspection
Reference: Spark Plug Removal and Installation:M13A
CAUTION:
When servicing the iridium/platinum spark plugs (slender center electrode type plugs), do not touch the center electrode to avoid damage to it. The electrode is not strong enough against mechanical force as it is slender and its material is not mechanically tough.
Inspect spark plug for:
• Electrode wear
• Carbon deposits
• Insulator damage
If any abnormality is found in nickel spark plug, 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.)
