Moroso 85668 Small Body Billet Aluminum Air Oil Separator with PCV Kit

The Moroso 85668 Small Body Air Oil Separator is a billet aluminum catch can solution designed to integrate directly into your vehicle's PCV (Positive Crankcase Ventilation) system. By intercepting excess crankcase vapors and residual oil mist before they re-enter the intake tract, this separator helps prevent detonation, carbon buildup, and oil deposits from forming on intake valves and manifold surfaces.

From the factory, most vehicles vent crankcase vapors and oil mist directly back into the intake manifold. Over time, this can lead to reduced engine performance, pre-ignition (detonation), and fouled intake components. The Moroso 85668 eliminates this problem by trapping contaminants in the separator body before they ever reach your intake.

Key Features:

• Small Body, Big Protection: Compact billet aluminum body fits a wide range of engine bays and plumbs inline with the existing PCV system
• Complete Installation Kit Included: Comes with 3/8" 90° inlet and outlet fittings, 60" of 3/8" rubber hose, a billet aluminum mounting clamp, and a mounting bracket
• Mess-Free Drain: Features a bottom drain with elbow fitting, making it easy to drain collected oil without spills
• Custom Appearance Ready: The billet aluminum body can be polished, chromed, or powder coated to match any custom engine compartment aesthetic
• Protects Intake Components: Prevents oil deposits from forming on intake valves, throttle bodies, and manifold surfaces, helping to maintain engine efficiency

The Moroso 85668 is an ideal upgrade for performance street vehicles, track cars, and turbocharged or supercharged applications where crankcase pressure and blow-by are elevated. Everything needed for inline PCV plumbing is included right in the box.
