The Beatrush Air Oil Separator Tank removes excessive oil from the engine ventilation system (blow-by) preventing it from ending up in intake system. As a secondary effect, the pressure inside the crankcase is decreased via discharged gases released through the oil cap.

All in all the Beatrush Air Oil Separator Tank System provides improved engine efficiency (improved gas mileage and cleaner emissions), a cleaner intake system, reduces oil consumption, and lowers chances of engine knock. If you're looking to improve the reliability and performance or your engine this is the best way to do so!
