SKS Spark Plug Inspection and Replacement

Required tools

Always wear safety glasses and nitrile gloves when servicing your Polaris snowmobile. To inspect and replace the spark plugs on your Polaris SKS, follow these steps:

1. Park the sled on a flat, level surface.

2. Remove each side panel by releasing the rubber strap and turning the two quarter-turn latches. Pull the panels out and lift up to remove.

3. Disconnect the two hood latches.

4. Lift the hood up slightly to gain access to the connector underneath.

5. Disconnect the connector and remove the hood from the sled.

6. Carefully remove both spark plug leads.

7. Clean the area around the spark plug to prevent debris from falling into the engine.

8. Remove the spark plug wrench from the spark plug holder.

9. Use the spark plug wrench to loosen the two spark plugs and remove from the vehicle.

10. Inspect the electrodes for wear and carbon buildup.

11. Inspect and adjust the spark plug gap if needed. The gap should be 0.027 inches (0.7 mm).

12. If necessary, replace with the recommended spark plug. The spark plug is NGK BPR 9ES, which is part number 3022082.

13. Install the spark plugs into the engine. Torque to 18 to 22 ft-lbs (24 to 30 Nm) with a 13/16-inch crowfoot wrench.

14. Reinstall the spark plug leads and ensure they are secure.

15. Reinstall the spark plug wrench in its holder.

16. Reinstall the hood panel, ensuring the tabs in front are properly engaged. 

17. Reconnect the connector underneath and verify it is secure.

18. Secure the two hood panel latches.

19. Reinstall both side panels by aligning the tabs at the bottom and top. Secure the rubber straps and the quarter-turn latches.

20. Finally, start the engine to ensure proper operation.
