MIA's Description

The GrimmSpeed Air Oil Separator is a performance aftermarket product designed to prevent harmful oil and vapors from entering the crankcase and head ventilation system in boxer engines. This helps prevent oil from coating the intake manifold and valves, which can lead to reduced fuel octane, increased chances of engine knock and detonation, worse emissions, and higher oil consumption.
