FX-350 High-Pressure Fuel Pump System

The Spool FX-350 Upgraded High-Pressure Fuel Pump System is a performance-focused enhancement engineered specifically for the Mercedes-AMG GT63 [M177] platform. This system builds upon the success of earlier models, providing a substantial 90% increase in fuel flow capacity and capable of delivering 35Mpa of pressure. This enhanced capability is crucial for pushing the limits of the M177 engine in high-performance applications. The system also promotes improved fuel atomization, resulting in finer fuel droplets that lead to more thorough air-fuel mixing, better combustion efficiency, increased power output, and potentially improved fuel economy and reduced emissions. Designed for flexibility and performance tuning, the FX-350 is 100% E85 compatible, allowing you to confidently run higher ethanol blends. The comprehensive kit includes two upgraded FX-350 high-pressure fuel pumps, a Bosch-spec 10-micron high-flow fuel filter for optimal debris protection, and upgraded fuel lines, along with all necessary installation hardware. An optional Spool Ethanol Content Monitor, which provides real-time fuel ethanol content and temperature readings via Bluetooth 4.0 and a mobile app, is also available. Please note that custom tuning is required to fully optimize the FX-350 system for your specific vehicle. Spool Performance recommends consulting with experienced tuners or utilizing their provided calibration details to ensure the best results. Additionally, it is important to ensure adequate low-pressure fuel supply, as a properly functioning low-pressure system is critical for the safe and effective operation of high-pressure pumps and injectors.
