Description:

This dual-purpose Oil Filler & Breather Box includes a system of internal baffles that separate the oil from the air and then returns the oil back to the engine. It mounts upright on the alternator stand, which was designed to look like part of the engine and also makes for easy oil filling.

The billet aluminum filler cap seals with an O’ring. Aluminum construction offers great looks and leak-free operation featuring an O’ring seal and button-head Allen top screws. Vent your valve covers, crankcase, air cleaners…whatever your requirements. Comes with attaching nut, O’rings, gasket and instructions. There are 4 threaded ports and all are 1/4" NPT.
