Reduce crankcase pressure, eliminate blow-by, and oil loss. High revving modified engines require more crankcase ventilation than the stock breather can supply. With the EMPI Aluminum Oil Breather Kit the blow-by oil is collected in the foam filter and the air vapors are vented to the atmosphere. New features include the EMPI logo cast in the top, improved heavy duty breather hose 1/2" ID, plus internal changes that includes a screen mesh shelf to elevate the foam filter element.
