Mishimoto Frozen Gray Baffled Oil Catch Can for BMW M3/M4 (F80/F82), 2015–2020

Description

The Mishimoto Baffled Oil Catch Can in Frozen Gray protects 2015–2020 BMW M3 and M4 S55 engines from blow-by contamination, reducing oil and vapor ingestion to help preserve intake and turbocharger reliability.

Designed by Mishimoto, a brand known for motorsports-grade cooling and reliability components, this baffled catch can kit addresses the long-standing blow-by issue that accompanies the S55 turbocharged platform introduced in 2015.

• Baffled internal design — Traps oil droplets and condensate before they re-enter the intake tract, minimizing carbon buildup and contamination on intake valves and turbocharger components.
• Frozen Gray finish — Durable coated appearance matched to high-end engine bays while resisting corrosion in everyday and track use.
• Vehicle-specific fit — Engineered for the 2015–2020 BMW M3/M4 S55 layout to ensure proper hose routing and mounting for a clean, secure installation.

What this delivers in practice: reduced intake contamination and lower risk of performance degradation over time, helping maintain consistent turbo response and engine longevity on both street and track-driven vehicles.

Installation notes: the kit is supplied as a vehicle-specific solution from Mishimoto and is intended to integrate with factory PCV and crankcase ventilation plumbing for the S55 engine family.

Mishimoto engineering focus: components designed for dependable function under repeated thermal cycles and the demands of turbocharged engines, providing a practical upgrade to mitigate blow-by-related maintenance and performance issues.
