Slp 14-134 Slp Powder Valve SkI-Doo

These trick flapper valves are installed in the top side of the airbox 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.
