Moroso 85519 Air Oil Separator - Large Body Billet Aluminum PCV System

The Moroso 85519 Air Oil Separator is a large-body crankcase ventilation system 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, reduces carbon buildup on intake valves, and keeps your intake manifold cleaner for improved performance and engine longevity.

Key Features:

• Billet aluminum construction with premium finish that can be polished, chromed, or powder coated to match your engine bay
• Plumbs inline with your PCV system to separate oil mist from crankcase vapors
• Large body capacity reduces maintenance intervals
• Bottom drain port with elbow fitting for easy, mess-free oil removal
• Complete installation kit included with 3/8-inch 90-degree inlet and outlet fittings
• Includes 60 inches of 3/8-inch rubber hose for flexible installation
• Billet aluminum mounting clamp and bracket included

Factory PCV systems recirculate oil-laden crankcase vapors directly back into the intake manifold, where they contribute to carbon deposits, reduced octane tolerance, and decreased performance. The Moroso 85519 eliminates this issue by capturing and condensing oil particles before they reach your intake system, resulting in cleaner combustion and better engine protection.
