Nostrum's High-Pressure Fuel Pump is an essential component of any high-horsepower build for the 2015-2021 WRX. You can't make power without enough fuel, and this guy delivers. This is essential for E85 which uses 30% more fuel and will quickly overrun the stock setup. The Nostrum high-pressure pump replaces the factory motor-driven pump. We also recommend using an upgraded in-tank pump.
Fits all 2015-2021 Subaru WRX.
