Spool Performance FX-350 Upgraded High Pressure Fuel Pump System | AMG GT63 [M177]

The Spool FX-350 Upgraded High-Pressure Fuel Pump System is a high-performance upgrade designed for the Mercedes-AMG GT63 [M177] platform. Building on the success of the previous FX-200, the FX-350 offers a 90% increase in flow capacity, delivering 35Mpa of pressure compared to the 25Mpa of the FX-200. This upgrade significantly enhances fuel flow, improves fuel atomization, and helps achieve higher horsepower while supporting bigger turbos and higher ethanol concentrations.

Key Features:

• 35Mpa Pressure & 40% More Flow:
  The FX-350 high-pressure fuel pump is engineered to provide 35Mpa of pressure, 90% more flow than the stock pump. This ensures your injectors are capable of flowing 40% more fuel, pushing the limits of the M177 engine for high-performance applications.

• Improved Fuel Atomization:
  The increased pressure of the FX-350 results in better fuel atomization, allowing for finer fuel droplets that mix more thoroughly with air, improving combustion efficiency. This means more power, better fuel economy, and reduced emissions.

• E85 Compatibility:
  The FX-350 is 100% E85 compatible, allowing you to run higher ethanol blends for performance tunes. It supports E85 fueling for vehicles running aggressive setups like larger turbos or upgraded fuel systems.

• Comprehensive Kit:
  The kit includes 2 upgraded FX-350 high-pressure fuel pumps, a Bosch spec 10-micron high-flow fuel filter, upgraded fuel lines, and all necessary hardware for installation. The 10-micron filter ensures optimal filtration, protecting your pump and injectors from debris without compromising fuel pressure.

• Ethanol Content Monitor (Optional):
  If selected, the kit includes a Spool Ethanol Content Monitor, which provides real-time readings of ethanol content and fuel temperature directly from your fuel tank. This monitor syncs with a free mobile app via Bluetooth 4.0, giving you precise data to ensure you're always using the correct ethanol blend for your tune.

• Tune Changes Required:
  Custom tuning is required to fully optimize the FX-350 system for your vehicle. Spool Performance can assist by providing calibration details to your tuner or connecting you with experienced tuners for the best results.

• Low Pressure Fuel Pump Upgrade:
  Proper low-pressure fueling is crucial for the safe and effective operation of high-pressure pumps and injectors. If necessary, plan for low-pressure upgrades to ensure fuel system longevity and prevent damage from low fuel supply.

Kit Includes:

• 2 x FX-350 High-Pressure Fuel Pumps

• 1 x Bosch 10-Micron High-Flow Fuel Filter

• Upgraded Fuel Lines

• All Necessary Installation Hardware

• (Optional) 1 x Ethanol Content Monitor Kit

• (Optional) Mobile App for Ethanol Content Monitoring
