Moroso 85486 Air Oil Separator Billet Aluminum PCV Crankcase Vent

The Moroso 85486 Air Oil Separator is a high-performance PCV system upgrade designed to capture excess crankcase vapors and residual oil mist before they can re-enter the intake tract. From the factory, most vehicles vent these crankcase vapors and oil mist directly back into the intake manifold, which can lead to detonation, reduced power, and harmful oil deposits forming on intake valves and manifold surfaces. The Moroso Air Oil Separator eliminates this problem by intercepting and collecting those contaminants inline.

Key Features:

• Plumbed inline with the vehicle's PCV system to capture crankcase vapors and oil mist before they re-enter the intake tract
• Helps prevent detonation and reduces oil deposit buildup on intake valves and manifold surfaces
• Precision-machined billet aluminum body that complements any engine compartment and can be polished, chromed, or powder coated for a custom appearance
• Includes 3/8" 90° inlet and outlet fittings, 60" of 3/8" rubber hose for inline plumbing, a billet aluminum mounting clamp, and a mounting bracket
• Bottom drain with elbow fitting allows virtually mess-free draining of collected oil

The Moroso 85486 is an ideal solution for performance builds, boosted applications, and daily drivers where intake cleanliness and engine protection are a priority. The complete hardware kit makes installation straightforward, and the durable billet aluminum construction ensures long-lasting performance under demanding conditions.
