Moroso 85488 Air Oil Separator Billet Aluminum PCV System

The Moroso 85488 Air Oil Separator is a high-performance engine component designed to capture excess crankcase vapors and oil mist before they can reenter your engine's intake tract. By intercepting these contaminants, this separator helps prevent detonation issues and keeps oil deposits from forming on intake valves and manifold surfaces.

Key Features:

• Billet aluminum construction with a premium finish that complements any engine bay—can be polished, chromed, or powder coated for a custom appearance
• Integrates directly into your vehicle's PCV (Positive Crankcase Ventilation) system to filter out oil mist that would otherwise recirculate through the intake
• Complete installation kit includes 3/8" 90-degree inlet and outlet fittings, 60 inches of 3/8" rubber hose, billet aluminum mounting clamp, and mounting bracket
• Bottom drain port with elbow fitting allows for easy, mess-free oil removal during maintenance
• Helps maintain cleaner intake components and reduces carbon buildup on valves

This air-oil separator is an essential upgrade for performance and modified engines where increased crankcase pressure can lead to excessive oil vapor in the intake system. Regular draining of collected oil ensures optimal performance and engine protection.
