Perrin Air Oil Separator For Use w/ TMIC 2008-2014 WRX / 2008-2021 STI

As oil builds up in your intercooler, its efficiency decreases, resulting in power reduction and potential engine damage through detonation. The Air Oil Separator mitigates the carbon buildup in the combustion chamber, intake valves, and intake tract, and directs crankcase blow-by back to the intake, though this can accumulate over time, leading to diminished power and wear on the valve train.

Features:

• Reduces the chances of detonation
• Traps oil from the crankcase ventilation before it enters the intake system
• Increases intercooler efficiency by reducing the amount of oil deposited into your intercooler and intake system
• Reduces carbon buildup in the combustion chamber, intake valves, and intake tract
• Separates engine oil from water vapors and allows the oil to drain back into the engine
