Mishimoto Baffled Oil Catch Can 15-20 BMW M3 / 15-20 M4 - Wrinkle Black | Direct Fit | Engine Protection

Overview

The Mishimoto Baffled Oil Catch Can is a direct-fit solution designed specifically for the 2015-2020 BMW M3 and M4 models equipped with the S55 turbocharged engine. This catch can system effectively captures and separates oil vapors and blow-by gases from the crankcase ventilation system, preventing them from contaminating the intake tract, intercooler, and VANOS system. It is ideal for enthusiasts looking to maintain engine cleanliness and performance longevity by reducing oil buildup and potential detonation risks.

Engineered with precision, the Mishimoto catch can features a CNC-machined billet aluminum lid with large inlet and outlet ports that align perfectly with the factory CCV hose dimensions. Its internal baffling and 50-micron bronze filter maximize oil separation efficiency. Unlike many air-oil separator systems that recycle blow-by gases back into the engine, this baffled catch can traps contaminants permanently, ensuring cleaner intake air and improved combustion quality.

For BMW M3 and M4 owners, this catch can offers tangible benefits by protecting critical engine components from oil contamination, which can degrade performance and reliability over time. The wrinkle black finish provides a durable, OEM+ aesthetic that integrates seamlessly into the engine bay. Installation is straightforward with included direct-fit hoses and a billet mounting bracket, making it a practical upgrade for both daily drivers and performance builds.
