- Outlet routes to the intake or turbo inlet pipe
- Suitable for properly configured MAF-based engines
- Coolant-heated separator helps prevent water condensation
Part number: 20-0219
Important installation requirements
The engine must have a suitable oil-pan return port. Mount the separator high enough for the bottom drain to sit above the engine return connection. Engine coolant must be routed through the AOS-R heating chamber. Confirm crankcase ventilation plumbing before installation.
