Maximize your Subaru's fueling potential with the DeatschWerks X2-Series Dual DW420 Fuel Pump Module, engineered specifically for 2008+ Subaru WRX and STI models. This high-performance module is a true plug-and-play solution, providing up to 400% more fuel flow over the factory system — while retaining full OE functionality and compatibility with the stock fuel tank.

Built for serious power builds and ethanol applications, the X2 module includes two DeatschWerks DW420 fuel pumps, supports return-style fuel systems, and preserves all factory features like the fuel level sensor, surge tank capability, and fuel tank capacity. Whether you're running E85 or high-octane race fuel, this module ensures reliable, consistent fuel delivery under all conditions.
