This is the GrimmSpeed Air Oil Separator. If you're familiar with modifying your vehicle, then you will know the importance of an air/oil separator, especially in a boxer-designed engine. The GrimmSpeed example comes with a unique design as it utilizes the factory oil filler cap location to maintain your PCV system while separating the harmful oil and vapors from the crankcase, as well as the head ventilation system. This will prevent oil from coating the intake manifold which will make can make its way onto the valves which will affect the octane rating which leads to detonation issues and performance issues.
