Moroso billet aluminum air/oil separator catch can for 1995–1999 BMW M3 applications. It intercepts oil-laden blow-by from crankcase ventilation to help reduce oil deposits in intake and related components on M3 engines. The M3-specific configuration is intended to fit common engine bay layouts for those model years and to make plumbing and mounting more straightforward.
