Spark Plug Inspection
Reference: SPARK PLUG REMOVAL AND INSTALLATION
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.
- Do not clean or adjust gap for the iridium / platinum spark plugs.
Inspect spark plug for the following:
- Electrode wear
- Carbon deposits
- Insulator damage
If any abnormality is found for nickel spark plugs, 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.
