Spark Plug: Testing and Inspection

INSPECT SPARK PLUG




a. Clean the spark plugs.

Air pressure: Below 588 kPa (6.0 kgf/sq.cm, 85 psi)
Duration: 20 seconds or less




b. Check the spark plug for any damage on its thread and insulator.
If damaged, replace the spark plug.

Recommended spark plug:
SK20HR11 (DENSO made)
ILFR6C11 (NGK made)




c. Check the spark plug electrode gap.
1. Using a spark plug gap gauge, measure the electrode gap.

Electrode gap: 1.0 to 1.1 mm (0.039 to 0.043 in.)
Maximum electrode gap: 1.3 mm (0.051 in.)

If the result is greater than the maximum, replace the spark plug.
