  • Never attempt to adjust the electrode gap of a used spark plug.
  • Replace with new spark plugs if extremely dirty due to sludge, etc.
  • Replace with new spark plugs if damaged at all.
  • Replace with a new spark plug if it has been struck or dropped.
  • When replacing with a new spark plug, do not remove the cap for protecting the spark plug tip until it is installed to the engine.

HINT:

Perform "Inspection After Repair" after replacing a spark plug.

NOTICE:

Never attempt to adjust the electrode gap of a used spark plug.

If the electrode gap is more than the maximum, replace the spark plug.

Standard Electrode Gap for New Spark Plug:

0.7 to 0.8 mm (0.0276 to 0.0315 in.)
