• Plumbed into a vehicle's PCV system to capture the excess crankcase vapors, residual oil mist and moisture from reentering the intake tract
• Vehicles from the factory vent these excess crankcase vapors, residual oil mist and moisture right back into the intake manifold which could cause: detonation, oil deposits in the intake tract including the valves themselves, and decreased intercooler efficiency
