IAG Performance and Nostrum have joined forces to develop the IAG Spec High-Flow Direct Fuel Injector Set by Nostrum. This fuel injector upgrade is a direct fit for 2022+ WRX, 2019+ Ascent, 2020+ Legacy XT Sport, and 2020+ Outback XT & Wilderness Subaru models equipped with the FA24 2.4L engine. These injectors not only boost fuel flow rate but also provide an OEM-quality spray pattern, ensuring an ideal air-fuel mixture for enhanced performance.

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.

• WHP potential on gasoline: 600 WHP (Calculated based on 290 BSFC, 40% injector DC, 10% driveline loss & 20 MPa fuel pressure)
• WHP potential on E85: 480 WHP (Calculated based on 360 BSFC, 40% injector DC, 10% driveline loss & 20 MPa fuel pressure)
• Tune Requirement: Yes
• Recommended Tuning Suite: COBB (WRX, Legacy, Outback, and Ascent – WRX only 2022+)
• Flow rate increase over Stock: 24% (compared to stock flow of 14.146 g/s)
• Flow rate: 17.5 g/s at 100 bar
• Max Operating Pressure: 200 bar / 20 MPa / 2900 psi
• Spray Pattern: OEM Comparable

The IAG Spec High-Flow Direct Fuel Injector Set by Nostrum is designed for a direct fit, and mount up just like the factory injectors.
