Description
The Mishimoto Oil Catch Can, part number MMOCC-RB, is a Performance grade catch can finished entirely in black to blend cleanly into any engine bay while doing serious work behind the scenes. Built with a 12mm port outside diameter and a 16 fl. oz. capacity, this catch can is engineered to intercept harmful oil before it can build up inside your turbocharger, intake manifold, intercooler, and piping.
Every performance-minded owner eventually runs into the same problem: oil vapor escaping through the PCV/CCV system and settling inside pressurized turbo plumbing, intercooler piping, and the intake tract. Left unchecked, that oil buildup can reduce combustion efficiency, lower intake temperatures inconsistently, and even contribute to couplers slipping off under boost. The Mishimoto Oil Catch Can addresses this directly by separating oil particles from PCV/CCV air before they ever reach these critical components, giving your car engine, intake system, and turbo plumbing a layer of protection that stock setups often lack. It’s a straightforward way to keep the parts of a car engine that matter most – the intercooler, intake manifold, and turbo piping – running cleaner for longer.
Vehicle Applications

Its compact footprint and included mounting bracket, hose, clamps, fittings, and hardware are intended to make it adaptable to a variety of engine bay layouts where oil blow-by from the PCV/CCV system needs to be captured before reaching the turbocharger, intake manifold, intercooler, or connecting piping.
