Oil Catch Can Baffled Black Sapphire 2015-2020 BMW M3 M4

Oil catch can for 2015-2020 BMW M3/M4 that reduces crankcase blow-by contamination to protect intake components and maintain engine reliability.

This Mishimoto Baffled Oil Catch Can Kit is purpose-built for the S55-equipped M3 and M4 introduced in 2015, addressing turbocharged-engine blow-by by capturing oil and contaminants before they reach the intake tract.

• Baffled can design — promotes separation of oil and vapors to limit re-entrainment, helping preserve intake and intercooler cleanliness.
• Vehicle-specific application — engineered for the 2015-2020 BMW M3 and M4 with the S55 engine to ensure correct mounting and routing for factory components.
• Mishimoto engineering — offered by Mishimoto to leverage the brand's reputation for motorsports-grade thermal and fluid-management solutions.

Why this matters: the S55's introduction of factory turbos increased susceptibility to crankcase gases being routed back into the intake. Capturing oil-laden vapors prevents buildup on intake valves and intercoolers, supporting consistent performance and reducing maintenance related to oil contamination.

Installation notes: the kit is supplied as a vehicle-specific assembly intended to integrate with existing PCV and intake plumbing on the specified BMW models. Use factory mounting points and routing for correct operation.
