1050x Top Feed Fuel Injectors

The COBB 1050x Top Feed Fuel Injectors are engineered to upgrade the fueling system of compatible Subaru vehicles, including WRX (2002-2014), WRX STI (2007-2021), Legacy GT (2007-2012), and Forester XT (2006-2013). These injectors deliver a nominal flow rate of 1065cc/min at 43.5psi, offering a significant increase in fuel capacity suitable for E85 and other performance-oriented applications. Constructed with corrosion-resistant internals, these injectors are compatible with all fuel types and feature replaceable inlet filters for extended service life. A key benefit is the matched set precision, maintaining a dynamic flow rate variance within 1% for reliable and consistent engine fueling. Installation is made straightforward with included plug-and-play adapters for stock fuel rails, and they offer data support for COBB's Accesstuner software, facilitating proper engine tuning. These injectors are an ideal choice for Subaru performance builds and upgrades, aiming to maximize engine potential. A proper tune is required for optimal performance and to ensure the engine runs correctly with the increased fuel flow.
