Show original supplier description
The IAG Spec High-Pressure Fuel Pump by Nostrum is a precision-engineered, direct-fit solution designed to optimize the fuel system for 2015-2021 Subaru WRX and 2014-2018 Forester XT models equipped with the FA20F 2.0L engine. This pump is fully compatible with E85 and blended ethanol fuels, offering higher resistance to detonation and cleaner, cooler combustion. Tuning is not strictly required but is highly recommended to achieve optimal performance; the system is also compatible with COBB engine management devices for further calibration. For the most effective high-performance fuel delivery package, this pump can be paired with the IAG Spec High-Flow Direct Fuel Injector Set by Nostrum (sold separately). Note that these fuel components are meticulously tested to meet or exceed OEM standards, and professional tuning via a Nostrum Certified Tuner is suggested for the best results.
