The Polaris Sportsman 800 is a popular ATV known for its reliability and performance. However, like any machine, it requires regular maintenance to keep it running smoothly. One of the most important maintenance tasks is changing the spark plugs. Spark plugs play a crucial role in the engine’s performance, and worn-out or fouled plugs can lead to decreased power, poor fuel efficiency, and even engine damage. In this article, we will guide you through the process of changing spark plugs on your Polaris Sportsman 800.
Why Change Spark Plugs?
Spark plugs are responsible for igniting the fuel-air mixture in the engine’s cylinders. Over time, they can become worn out, fouled, or corroded, which can affect the engine’s performance. Here are some reasons why you should change your spark plugs:
| Reason | Consequences |
|---|---|
| Worn-out spark plugs | Decreased engine power, poor fuel efficiency, and increased emissions |
| Fouled spark plugs | Engine misfires, rough idling, and decreased performance |
| Corroded spark plugs | Increased risk of spark plug failure, engine damage, and costly repairs |
Tools and Materials Needed
To change the spark plugs on your Polaris Sportsman 800, you will need the following tools and materials:
- Spark plug socket (14mm or 5/8″ drive)
- Spark plug gap gauge
- New spark plugs (NGK or equivalent)
- Spark plug wire puller (optional)
- Ratchet and extension
- Torx screwdriver (for spark plug wire boot removal)
- Spark plug cleaner (optional)

Take the new spark plug and insert it into the cylinder head. Make sure it’s seated properly and then turn it clockwise until it’s snug. Do not overtighten the spark plug.
Step 6: Reinstall the Spark Plug Wire
Take the spark plug wire and reattach it to the new spark plug. Make sure it’s securely seated and then tighten the retaining screw. (See Also: Where Is the Spark Plug on a Lawn Mower? A Step By Step Guide)
