The Moroso air/oil separator catch can for 2015–up Subaru WRX is a small-body billet aluminum unit finished in black that captures oil and blow-by before it reaches the intake. It provides a compact reservoir to separate condensates and help maintain cleaner intake and combustion systems. The black finish offers a low-profile look while supporting tidy hose routing.
