Moroso Air-Oil Separator Small Body Black, Subaru WRX, 2015-UP

• 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
• Increases engine performance from cleaner intake air
• Air-Oil Separators have billet aluminum bodies with internal baffling and mesh media
• Includes heavy duty brass inlet and outlet fittings, Fuel/Emission/PCV Vapor hose, stainless steel mounting bracket and billet aluminum mounting clamp for the body of the separator
