SPARK PLUGS
SPARK PLUG RECOMMENDATIONS
Refer to the Specifications section for the recommended spark plug type and
gap for your vehicle.
NOTICE
Using non-recommended spark plugs can result in serious engine damage.
Always use POLARIS-recommended spark plugs.
PLUG CONDITION
TORQUE SPECIFICATION
New Spark Plug 12 Nm (9 ft-lbs)
Previously Installed Spark Plug 12 Nm (9 ft-lbs)
SPARK PLUG INSPECTION
Spark plug condition is indicative of engine operation. Check the spark plug
firing end condition after the engine has been warmed up and the vehicle has
been driven at higher speeds. Immediately check the spark plugs for correct
color.
CAUTION
A hot exhaust system and engine can cause burns. Wear protective gloves
when removing a spark plug for inspection.
NORMAL SPARK PLUG
The normal insulator tip is gray, tan or light brown. There will be few combustion
deposits. The electrodes are not burned or eroded. This indicates the proper
type and heat range for the engine and the service.
The tip should not be flaky and white. A white insulator tip indicates overheating,
caused by use of an improper spark plug or incorrect fuel.
WET FOULED SPARK PLUG
The wet fouled insulator tip is black. A damp oil film covers the firing end. There
may be a carbon layer over the entire nose. Generally, the electrodes are not
worn. General causes of fouling are excessive oil, use of non-recommended oil
or incorrect throttle body adjustments.
