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 log cast into the top, improved heavy duty breather hose with 1.2" ID plus internal changes that include a screen mesh shelf to elevate the foam filter.
