Perrin [08-14 WRX, 08-21 STI, 05-09 LGT/OBXT] Air Oil Separator Red w/ TMIC

The PERRIN Air Oil Separator increases intercooler efficiency by reducing the amount of oil deposited into your intercooler and intake system. As blow-by/oil builds up inside your intercooler, the less efficient it becomes due to less heat being transferred away from your engine, leading to power loss and detonation which can be damaging to your engine. This unit is designed to work with the stock top mount intercooler (TMIC).

• Traps oil from crankcase ventilation before it enters the intake system
• Reduces carbon build-up in the combustion chamber, intake valves, and intake tract
• Coolant-heated base plate keeps the AOS at the same temperature as the engine and blow-by gases, decreasing water condensation so oil and water vapor separate and pass through the can
• Separates engine oil from water vapors and drains it back into the engine - not a catch can
• Eliminates nearly all sludge build-up in the AOS body, drastically reducing how often it must be cleaned
• Red powder-coated finish; car-specific bracket, hoses, fittings and all hardware included
• Fits 2008-2014 WRX and 2008-2014 WRX STI with the stock top mount intercooler
• Manufacturer part number: PSP-ENG-606RD
