Moroso 85674 Air Oil Separator Small Body Billet Aluminum PCV System

The Moroso 85674 Air Oil Separator is designed to be plumbed into your vehicle's PCV system to capture excess crankcase vapors and residual oil mist before they can reenter the intake tract. Factory PCV systems typically vent these vapors and oil directly back into the intake manifold, which can cause detonation issues and oil deposits to form throughout the intake tract, including on the valves themselves.

Key Features:

• Small body billet aluminum construction complements any engine compartment and can be polished, chromed, or powder coated for a custom appearance
• Complete installation kit includes 3/8" 90-degree inlet and outlet fittings, 60 inches of 3/8" rubber hose for inline plumbing, billet aluminum mounting clamp, and mounting bracket
• Bottom drain with elbow fitting allows for virtually mess-free draining of collected oil
• Helps prevent oil contamination in intake system for improved engine performance and longevity
• Reduces carbon buildup on intake valves and combustion chambers

This compact air-oil separator provides an effective solution for keeping your intake system clean while maintaining proper crankcase ventilation. The high-quality billet aluminum construction ensures durability and long-term reliability in demanding automotive applications.
