550cc Side Feed Fuel Injector Set

The Subaru 16600-AA170 fuel injectors are a direct replacement for your vehicle's original side-feed injectors, offering an increased flow rate of 550cc/555cc per minute at 43.5 PSI. These high-impedance injectors (11.5 ohms) feature a 4-hole nozzle for improved fuel atomization and are compatible with E85 fuel. Manufactured to meet OE standards, each injector has undergone rigorous testing, including pressure/leak testing and spray/flow testing, to ensure precise fuel delivery and internal coil resistance matching. This ensures a 100% exact match to the original specifications. These injectors are designed for a direct fitment on models equipped with EJ255, EJ257, and EJ20T engines. Fitment includes Subaru Impreza WRX (2006-2014), Forester XT (2004-2013), Legacy GT (2005-2013), Outback XT (2005-2009), Baja Turbo (2004-2006), and the SAAB 9-2X (2006 only). They are also compatible with various international models including Legacy/Outback (2007-Present), Impreza (2005-Present), and Forester (2005-2010), as well as specific US Market Impreza WRX STi MY 2004-2007 and 2008-2016. This upgrade can lead to increased fuel economy, improved throttle response, and a smoother idle.
