Description

The IAG Performance V3 Street Series Air/Oil Separator is designed for 2006-2007 Subaru WRX and 2004-2007 Subaru STI models. This Air/Oil Separator (AOS) system captures oil suspended in the engine's PCV gasses, allowing it to drain back into the crankcase. It features custom-length SAE Quick Connection lines for easier installation and reduced leak risk.
