Moroso 85515 Air Oil Separator Large Body Billet Aluminum

The Moroso 85515 Air Oil Separator is a large body billet aluminum unit designed to capture excess crankcase vapors and residual oil mist before they can reenter your engine's intake system. When plumbed into the PCV system, this separator prevents oil deposits from forming in the intake tract, manifold, and on valves themselves—eliminating a common cause of detonation and performance loss.

Key Features:

• Large capacity billet aluminum body that can be polished, chromed, or powder coated for a custom appearance
• Includes 3/8" 90-degree inlet and outlet fittings for easy installation
• Complete installation kit with 60 inches of 3/8" rubber hose for inline plumbing
• Billet aluminum mounting clamp and bracket included for secure installation
• Bottom drain with elbow fitting for mess-free oil collection and disposal
• Prevents oil contamination in intake manifold that factory PCV systems allow

This air oil separator is an essential upgrade for performance and modified engines where crankcase pressure and oil vapor are concerns. The large body design provides superior separation capacity compared to smaller units, making it ideal for high-performance street and racing applications.
