Upgrade your 2015-2020 BMW M3/M4 with the Mishimoto Baffled Oil Catch Can Kit, designed to protect your engine from blow-by issues that come with turbocharged powerplants. The S55 engine in these M cars brought turbos from the factory, but also the age-old problem of blow-by. This kit leverages Mishimoto's patent-pending 2-Port Compact Baffled Oil Catch Can technology, featuring a 50-micron bronze filter and internal baffle to effectively separate oil from crankcase vapors.
Unlike most air-oil-separator systems, Mishimoto's catch cans don't heat up, allowing all blow-by, including low-octane oil vapors and contaminated fuel vapors, to condense in the can. With two aluminum barb fittings connecting the hoses to the can, this kit keeps blow-by out of your engine permanently, offering superior protection.
