Description
The Mishimoto Baffled Oil Catch Can Kit (MMBCC-F80-15CMG) is purpose-built for the S55-powered BMW M3, M4, and M2 Competition, giving these turbocharged compact M cars a dedicated line of defense against oil blow-by. Built around the Mishimoto 2-Port Compact Baffled Oil Catch Can (US Patent No. D966,372 S), this kit pairs a 50-micron bronze filter with an internal baffle to separate oil from crankcase vapors before they ever reach the intake tract.
As a longtime maker of car engine parts and other components of an automobile engine, Mishimoto engineered this catch can with a CNC-machined, twist-off lid featuring large inlet and outlet ports sized to match the inner diameter of the factory CCV hose, so crankcase vapors flow efficiently into the can. Because the can is not heated, oil vapor, low-octane fuel vapor, and contaminated fuel condense and stay trapped inside rather than draining back into the oil pan the way many air-oil-separator systems do. This helps defend the intercooler, intake system, and VANOS system from oil blow-by and helps maintain proper octane levels to reduce potential detonation. For anyone digging into the parts of a car engine that quietly protect automobile combustion, a baffled catch can like this is one of the more overlooked yet essential engine parts for car reliability.
Vehicle Applications
This catch can kit is a direct fit for the 2015-2018 BMW M3, the 2015-2020 BMW M4 Coupe and Convertible (including the 2016 BMW M4 GTS Coupe and the 2019-2020 BMW M4 CS Coupe), and the 2019-2020 BMW M2 Competition. Every one of these applications shares the turbocharged S55 engine across the F80, F82, F83, and F87 chassis codes, and the kit’s hoses and mounting bracket are application-specific so installation requires no modification to the factory engine cover.
