Perrin Air Oil Separator Neon Yellow w/ FMIC

• 2005-2009 Subaru | Legacy GT
• 2002–2014 Subaru | WRX
• 2004–2021 Subaru | WRX STI

Keep oil out of your intake tract with the PERRIN air oil separator for 2002-2014 WRX, 2004-2021 STI, and 2005-2009 Legacy GT running a front mount intercooler. By trapping crankcase blow-by before it reaches the intake, the AOS reduces carbon buildup on intake valves and in the combustion chamber, keeps the intercooler working efficiently, and helps prevent detonation. The coolant-heated base plate keeps the can at engine temperature to cut condensation and sludge, so it needs cleaning far less often. Finished in neon yellow powder coat.
