High-Flow Direct GDI Fuel Injector Set

The IAG Performance Spec High-Flow Direct GDI Fuel Injector Set by Nostrum is engineered as a direct-fit upgrade for the 2022-2025 Subaru WRX and other FA24 2.4L engine models, including the 2019+ Ascent, 2020+ Legacy XT, and 2020+ Outback XT Wilderness. This set provides a 24% increase in fuel flow compared to stock injectors, enabling support for higher horsepower and boost levels, with claimed support for up to 600 WHP on gasoline and 480 WHP on E85. A unique feature includes an extended harness connector on the Cylinder 1 injector to accommodate the FA24's coolant crossover pipe without requiring modifications. These injectors are fully compatible with E85 and ethanol blends, which can lead to cooler combustion and increased resistance to detonation, offering greater tuning flexibility. Professional ECU tuning is required to optimize fueling, cold starts, and overall drivability after installation, and the set is compatible with COBB AccessPort tuning. Included in the set are four direct-fit GDI fuel injectors, four injector clips, and installation instructions. While physical installation is straightforward for experienced DIYers and requires no modifications, professional calibration is strongly recommended.
