To inspect and replace the spark plugs on your Polaris INDY XC, follow these steps:

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

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

3. Next, 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. Next, carefully remove both spark plug leads.

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

8. Next, remove the spark plug wrench from the spark plug holder.

9. Then use the spark plug wrench to loosen the two spark plugs and remove them 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. Refer to your Owner’s Manual for recommended spark plugs. 

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

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

15. Also reinstall the spark plug wrench in its holder.

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

17. Then reconnect the connector underneath and verify it is secure.

18. Continue by securing the two hood panel latches.

19. Then reinstall both side panels by aligning the tabs at the bottom and top. Secure the rubber strap and the quarter-turn latches.

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