Spool Performance AMG S63 [M177] Spool FX-350 Upgraded High Pressure Pump Kit

The Spool Performance FX-350 High-Pressure Fuel Pump Kit is the pinnacle of fuel system upgrades for the Mercedes-AMG S63 [M177]. This advanced system offers unmatched fuel delivery, surpassing the previous FX-200 model in both pressure and flow capacity. Designed to provide higher pressure at 35Mpa compared to the FX-200's 25Mpa, the FX-350 boosts fuel flow, enhances fuel atomization, and ensures optimal performance for high-powered AMG builds.

Key Features of the FX-350:

• 35Mpa Fuel Pressure: Delivers increased flow and fuel pressure, ensuring up to 40% more fuel flow before injector limitations.
• Improved Fuel Atomization: Finer fuel droplets ensure better combustion, enhancing power output, fuel efficiency, and reducing emissions.
• 90% More Flow: Provides significantly more fuel to support bigger turbos and higher ethanol blends like E85.
• Superior Filtration: Includes a 10-micron Bosch-spec high-flow fuel filter, offering the best filtration without pressure drops.

What’s Included:

• 2x FX-350 upgraded high-pressure fuel pumps
• Ethanol Content Monitor kit (optional) with a mobile app
• Bosch spec 10-micron high-flow fuel filter
• Upgraded fuel lines (E85 compatible) and all necessary installation hardware
• Spool 10-micron filter unit for enhanced protection against debris

Why You Need the FX-350:

The stock high-pressure fuel pump (HPFP) on M177 engines limits performance when tuning for higher power outputs. The FX-350 solves this issue, allowing for higher horsepower, bigger turbos, and higher ethanol blends without sacrificing fuel supply or risking engine damage. This kit is essential for anyone seeking to push the limits of their AMG S63.

Additional Considerations:

• Tuning Required: Calibration changes are necessary for optimal performance. These changes should be applied before starting the vehicle to avoid warranty issues.
• Low-Pressure Fuel Pump (LPFP) Upgrade Recommended: Proper low-pressure fueling ensures the longevity of your HPFP and injectors. Spool Performance highly recommends upgrading the LPFP to prevent damage from low fuel pressure.

This kit offers everything you need to take your Mercedes-AMG S63 M177 to the next level, ensuring maximum performance with reliability and efficiency.
