Mishimoto Oil Catch Can Baffled White 15-20 BMW M3 M4

Oil catch can that protects the intake system on 2015–2020 BMW M3/M4 (S55) by managing blow-by and helping preserve engine reliability.

This Mishimoto Baffled Oil Catch Can Kit is engineered as a maintenance and reliability component to address the increased incidence of blow-by introduced with the factory turbocharged S55 engines in the 2015 compact M models. It is presented as a complete kit from Mishimoto, a brand known for motorsports-grade thermal and fluid-management components.

Key features and why they matter

• Baffled can design — Controls oil and vapor movement inside the can to reduce carryover into the intake, helping maintain intake and intercooler cleanliness.
• Vehicle-specific fitment (2015–2020 BMW M3/M4) — Tailored application reduces install complexity and ensures routing and mounting align with factory service locations for the S55 platform.
• Complete kit packaging — Supplied as a kit to provide the necessary components for installation and integration with the engine’s crankcase ventilation system.
• White finish — Offers a clean, serviceable appearance suitable for engine-bay installations where visual inspection is desirable.
• Mishimoto brand engineering — Designed and backed by a supplier with experience in high-performance and motorsports cooling and fluid solutions.

Performance and service considerations

The catch can focuses on trapping oil and condensate from blow-by before they re-enter the intake tract. For turbocharged S55 engines, this helps limit deposits downstream of the crankcase ventilation path, supporting consistent boost response and keeping intake components in cleaner condition over time.

Installation considerations: the product is supplied as a kit intended for direct application to the 2015–2020 BMW M3 and M4 models. Refer to the included installation materials and follow standard safety and service procedures when removing and routing crankcase ventilation lines.
