Moroso 85647 Air/Oil Separator Kit Twin Small Body Black Anodized PCV Valve Hose

The Moroso 85647 is a twin small body air/oil separator kit specifically designed for 2008-2014 Subaru STI models equipped with front mount intercoolers. This complete catch can system is plumbed into the vehicle's PCV system to capture excess crankcase vapors, residual oil mist, and moisture before they can reenter the intake tract.

Key Features:

• Twin small body design with black anodized billet aluminum construction measuring 2.125 inches in diameter and 4.5 inches in height per separator
• Internal baffling and mesh media effectively capture oil vapor and prevent recontamination of intake air
• Two-piece body design unscrews for easy draining of collected oil
• Includes heavy duty brass inlet and outlet fittings with 3/8-inch NPT connections
• Complete kit includes fuel/emission/PCV vapor hose, stainless steel mounting bracket, and billet aluminum mounting clamps
• Prevents detonation and oil deposits from forming in the intake tract and on valves
• Maintains intercooler efficiency by keeping oil out of the cooling system

This dual separator configuration is required for proper crankcase ventilation on Subaru STI applications. By removing oil vapor from the intake air, this system helps increase engine performance and protect critical engine components from contamination.
