Product Description

The Injector Dynamics 1050.18.04.36.11.4 ID1050-XDS injector set is a high-performance upgrade designed for Subaru BRZ and Toyota 86/Scion FR-S vehicles equipped with FA20 (and in some cases FA24) engines. These injectors deliver approximately 1065 cc/min of fuel flow, making them ideal for naturally aspirated and forced induction builds where stock injectors no longer meet fueling demands. With advanced Dual Slope Dynamic Matching (XDS) technology, these injectors offer improved cylinder-to-cylinder consistency, smoother throttle response, and better drivability across the powerband.

Built with corrosion-resistant internals and USCAR connectors, this set supports gasoline and ethanol blends, and the compact short-body design fits into tight engine bays common on BRZ/86 platforms. The included 11 mm machined top and WRX-16B bottom adapters ensure proper fitment with compatible fuel rails. Always verify that your specific vehicle's fuel rail and harness match these injector specifications before installation. Professional ECU tuning is recommended after installation to achieve optimal fueling and performance gains.
