The EMPI dual purpose oil filler and breather box includes a system of internal baffles that separate the oil from the air then returns the oil back to the engine.
Mounting upright on the alternator stand is not only aesthetically appealing but makes filling oil much easier.
Billet aluminium construction includes x4 threaded ports which are 1/4" NPT, supplied with attaching nut, o-rings, gaskets and instillation instructions.
