MAINTENANCE

Spark Plugs

It’s very important to use the correct spark plug for your machine. A

spark plug with a heat range too high will cause engine damage. A

spark plug with a heat range too low will cause excessive fouling and

engine malfunctioning.
In selecting a spark plug heat range for production, a manufacturer

assumes that the engine will be operated under extreme heavy duty

conditions and selects a spark plug that will protect the engine from

internal damage if the purchaser actually does operate the engine in this

manner. This selection could cause the customer who normally

operates the engine under medium or light duty to have spark plug

failure. Refer to your Owner’s Manual Supplement for the specific

spark plug to be used in your machine.

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.
S

Use recommended spark plugs with the proper gap. Refer to your

Owner’s Manual Supplement for specific information.

Spark plug torque is 18-22 ft. lbs. (24-30 Nm).

Always carry spare spark plugs in case of an emergency.

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. See your Owner’s Manual Supplement.

CAUTION

Using non-recommended spark plugs can result in serious engine

damage. Always use Polaris-recommended spark plugs.
