Mishimoto’s baffled oil catch can kit for 2007–2010 BMW N54 installs on the CCV side and uses a 2-port Compact Baffled Can with a 50‑micron bronze filter and internal baffling to reduce carbon buildup. A CNC-machined lid matches CCV hose dimensions, and the kit includes direct-fit hoses and a serviceable bracket so no engine cover modifications are required. It aims to keep oil out of the intake and protect engine components.
