EMISSION CONTROL SYSTEMS

Noise Emission Control System

Do not modify the engine, intake or exhaust components, as doing so may affect

compliance with state and local noise level requirements.

Spark Arrestor

Your Polaris vehicle has a spark arrestor that was tested and approved in accordance with

the USDA Forest Service Standard 5100-1C. Federal law requires that this spark arrestor

be installed and functional when the vehicle is operated on public lands.

Crankcase Emission Control System

This engine is equipped with a closed crankcase system. Blow-by gases are forced back to

the combustion chamber by the intake system. The system does not allow the blow-by

gases to enter the atmosphere.
