These trick flapper valves are installed in the back side of the airbox on Polaris 6/7/800 models to provide additional airflow to the engine. They are activated by airbox vacuum. When the stock intake begins to plug in deep powder snow conditions, these valves open to deliver the necessary airflow that the engine demands. This substantially improves consistency when running in deep powder snow conditions. Sold per pair.

Not for race chassis.

Powder Valve Pre-Filter will only work with 6/7/800 HO IQ, IQ RMK and Axys/Patriot
