Required Tools and Supplies: 

  • Spark Plug Wrench
  • 13/16-Inch Crowfoot
  • Torque Wrench
  • Safety Glasses
  • Nitrile Gloves
  • Shop Rags

Always wear safety glasses and nitrile gloves when servicing your Polaris snowmobile. To inspect and replace the spark plugs on your model year 2022 and newer INDY XC, INDY XCR or INDY Adventure, follow these steps:

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

2. Remove both side panels by turning the three quarter-turn latches. Pivot the panels away from the sled, and pull out 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 plugs to prevent debris from falling into the engine.

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

9. Using a spark plug wrench, loosen the two spark plugs, and remove them from the vehicle. If reusing, take note of the cylinders they were installed in for reinstallation.

10. Inspect the electrodes for wear and carbon buildup. They should have a sharp outer edge with no rounding or erosion. 

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

12. If necessary, replace with the recommended spark plug. Refer to your Owner’s Manual for the recommended plugs. 

13. Install the spark plugs into the engine. Torque to 22 ft-lbs (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. Continue by securing the two hood panel latches.

19. Reinstall both side panels by inserting the upper tab and pivoting in to engage the lower tab. 

20. Latch the three quarter-turn latches to secure each panel.

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