IAG Spec High-Pressure Fuel Pump By Nostrum - Fits 2022-2025 WRX
IAG Performance and Nostrum have teamed up to deliver the IAG Spec FA24 High-Pressure Fuel Pump by Nostrum. This direct-fit pump is tailored for 2022+ WRX, 2019+ Ascent, 2020+ Legacy XT Sport, and 2020+ Outback XT & Wilderness Subaru models equipped with the FA24 2.4L engine. As the first and only complete high-pressure fuel pump upgrade for FA24 engines, this Nostrum pump offers increased fuel flow, optimizing your engine’s power output and performance.
Delivering up to 37% more fuel flow than the stock Subaru pump, the IAG Spec FA24 High-Pressure Fuel Pump by Nostrum provides plenty of fuel to allow for more boost at lower RPMs, resulting in an improvement in low-end torque. For the ultimate fuel delivery package, use this pump in conjunction with the IAG Spec FA24 Hi-Flow Direct Fuel Injector Set by Nostrum. These injectors offer a 24% increase in flow over OEM Subaru injectors, opening up new potential for horsepower gains.
The IAG Spec FA24 High-Pressure Fuel Pump by Nostrum is compatible to run on E85 and blended ethanol fuels. E85 not only boosts horsepower but also offers a multitude of additional benefits; it burns cleaner and cooler than regular gasoline, it has a higher resistance to detonation (knock), and it’s a cost-effective option for race fuel. When properly tuned and paired with E85-compatible fuel system components, this pump ensures consistent, high-performance fuel delivery, even under the tough demands of E85 and ethanol blends.
