Forge Oil Catch Can for Audi RS3 8V FL and TTRS 8S

Excess crankcase pressure is vented from the crankcase through the PCV system, where it is drawn into the intake manifold and returned by the engine. This recirculated air contains aerated oil from the crankcase which is burned by the engine. This oil catch tank system removes aerated oil so that it can be drained and recycled to keep your engine as clean and efficient as possible !
