Spark Plug Condition Inspection

• Remove the spark plugs (see Spark Plug Replacement in the Periodic Maintenance chapter).
• Visually inspect the spark plugs.

If the spark plug center electrode [A] and/or side electrode [B] are corroded or damaged, or if the insulator [C] is cracked, replace the plug.

If the spark plug is dirtied or the carbon is accumulated, replace the spark plug.

• Measure the gap [D] with a wire-type thickness gauge.

If the gap is incorrect, replace the spark plug.

Spark Plug Gap: 0.8 0.9 mm (0.031
0.035 in.)

• Use the standard spark plug or its equivalent.

Standard Spark Plug Type: NGK CR9EIA-9
