Spark Plug Recommendations

NOTICE
Using non-recommended spark plugs can result in serious engine damage. A spark plug with a heat range too high will always cause engine damage if the engine is operated in conditions more severe than intended for that plug. Always use the spark plugs recommended for your snowmobile.
A new engine can cause temporary spark plug fouling due to the preservative added during the assembly process. Avoid prolonged idle speeds, which cause plug fouling and carbonization.
Refer to the Specifications chapter for the specific spark plug to be used in your snowmobile.
Change the spark plugs at the intervals outlined in the Periodic Maintenance section.
  • Use recommended spark plugs with the proper gap. Refer to the specifications section for the specific spark plug to be used in your snowmobile.
  • Use only resistor-type spark plugs.
  • Torque spark plugs to specification.
    TORQUE

    Spark Plug

    18-22 ft-lbs (24-30 N·m)
  • Always carry spare spark plugs.

Spark Plug Condition

Normal Plug

The normal insulator tip is gray, tan or light brown. There will be few combustion deposits. The electrodes are not burned or eroded. This indicates the proper type and heat range for the engine and the service.
TIP
The tip should not be white. A white insulator tip indicates overheating, caused by use of an improper spark plug or incorrect carburetor/throttle body adjustments.

Wet Fouled Plug

The wet fouled insulator tip is black. A damp oil film covers the firing end. There may be a carbon layer over the entire nose. Generally, the electrodes are not worn. General causes of fouling are excessive oil or use of non-recommended injection oil.

Spark Plug Removal and Replacement

  1. Remove the spark plug cap.
  2. Using the special wrench provided in the tool pouch, rotate the spark plug counter-clockwise to remove.
  3. Reverse the procedure for spark plug installation.
  4. Torque to 18–22 ft. lbs. (24–30 Nm.).
  5. Reinstall the spark plug cap.
