BMW M57 Crankcase Ventilation Adapter

BMW M57 Crankcase Ventilation Adapter

The BMW M57 crankcase ventilation adapter is designed for custom M57 engine swap and performance applications where the factory crankcase ventilation layout needs to be modified, simplified or connected to a custom breather system.

This adapter can be used when building a standalone M57 setup, custom intake system, top mount turbo layout or engine conversion where the original BMW engine bay packaging is no longer suitable.

Typical use cases

• BMW M57 engine swap projects
• Custom crankcase ventilation routing
