Delivering up to 24% more fuel flow than the stock Subaru injectors, the IAG Spec High-Flow Direct Fuel Injector Set maintains an OEM-quality spray pattern for reliable cold starts, idle stability, and quick throttle response. Pair these injectors with the IAG Spec High-Pressure Fuel Pump by Nostrum for 2022+ Subaru WRX for the ultimate fuel delivery package. This pump delivers a 37% flow increase over the OEM pump, unlocking new horsepower potential.
The IAG Spec High-Flow Direct Fuel Injector Set 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 alternative for race fuel. When properly tuned and paired with E85-compatible fuel system components, these injectors ensure consistent fuel delivery that can handle the demands of E85 and ethanol blends.
