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 2015-2021 WRX and 2014-2018 Forester XT Subaru models equipped with the FA20F 2.0L 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 10% 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 2015-2021 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 option 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.
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. Nostrum’s precise fitment, complete with all the necessary fittings and hardware ensures a straightforward installation without the need for modifications. The installation process takes about an hour and requires only basic hand tools for those with moderate mechanical skills.
Please note that tuning is required after installation of the IAG Spec High-Flow Direct Fuel Injector Set. Please see below for a list of Nostrum Certified Tuners. The High-Flow Injectors and Pumps are compatible with the stock Subaru ECU, and can also be adjusted with COBB engine management devices for even better results. (Fuel pump sold separately).
