The AMS Alpha Air/Oil Separator is engineered to protect your VR38 engine by removing oil vapor from the crankcase before it contaminates your intake tract. By eliminating blow-by, this system prevents power loss, reduces harmful detonation risk, and keeps your intake clean, especially under high boost or ethanol-based fueling.

Why It Matters

Even on stock GT-Rs, oil vapor accumulates in the intake due to the factory PCV system. Under boost or with modified engines, oil can exit blow-off valves, creating oily buildup and a mess in the engine bay. The Alpha Air/Oil Separator addresses this by capturing and returning oil directly to the pan, keeping your engine bay clean and your VR38 running efficiently.

Maintenance-Free Oil Recovery

Unlike standard catch cans that require manual draining, AMS’s 3-tier design separates oil from crankcase air and automatically drains it back into the oil pan. A check valve ensures proper flow and prevents overflow, eliminating maintenance worries and avoiding potential low oil conditions.
