Show original supplier description
The IAG Performance V3 Street Series Air Oil Separator (AOS) Replacement Line and Hardware Kit is a premium solution for maintaining your Subaru's forced induction system. This kit provides all the hoses, lines, and hardware that were originally supplied with the IAG Street Series V3 AOS, ensuring a seamless replacement and continued optimal performance. Designed for specific Subaru models including the 2008-2014 WRX, 2008-2021 STI, and 2005-2009 Legacy GT, this kit features durable components engineered exclusively for the V3 AOS. Installation is straightforward, making it suitable for both routine maintenance and performance upgrades. It helps keep your engine bay clean and your forced induction system running efficiently. Please note that this kit does not include the upper Street Series breather fitting. It is also explicitly not compatible with the V2 AOS. Enthusiasts seeking OEM-level fitment and reliability will find this kit essential for maintaining their vehicle's performance.
