Spool Performance FX-170 Upgraded High Pressure Fuel Pump System | C63 AMG [M177]

The Spool Performance FX-170 Upgraded High Pressure Fuel Pump is engineered specifically for the Mercedes-AMG C63 M177 engine, providing 50% more flow compared to the stock pump. This high-performance fuel pump is E85-compatible, plug-and-play, and does not require any cutting or splicing during installation. Designed to fuel bigger turbos and support higher ethanol blends, the FX-170 ensures your high-performance AMG C63 receives the fueling capacity necessary to meet your power goals.

Key Features:

• 50% More Flow Than Stock:
  The FX-170 pump features an enlarged bore size, delivering approximately 50% more flow compared to the stock high-pressure fuel pump. This increase in flow is critical for supporting higher horsepower, larger turbos, and higher ethanol content fuels, such as E85.

• E85 Compatibility:
  The FX-170 is fully compatible with E85 and other ethanol-based fuels, ensuring that your C63 M177 runs at peak performance, even under high-ethanol concentration conditions.

• Plug-and-Play Installation:
  Installation is easy and requires no cutting or splicing. Simply remove the stock pump and replace it with the FX-170 for an upgrade that’s hassle-free and engineered for seamless integration.

• Supports Bigger Turbos & Higher Ethanol Blends:
  The additional flow allows the FX-170 to accommodate larger turbo setups and the fueling needs for E85 or other high-ethanol mixtures. This makes it the ideal pump for tuning and performance builds on the C63 M177 platform.

Kit Includes:

• 2 x FX-170 Upgraded High-Pressure Fuel Pumps
• 1 x Ethanol Content Monitor Kit (if option selected)
• 1 x Bosch Spec 10-Micron High Flow Fuel Filter

Spool 10-Micron Filter Unit:

The Spool 10-micron filter ensures optimal fuel filtration without restricting flow. Designed to protect your high-pressure pump and injectors, it filters out debris while allowing smooth, uninterrupted fuel flow. This helps maintain the longevity and reliability of your C63 M177’s fuel system.

Spool Ethanol Content Monitor:

The Spool Ethanol Content Monitor (ECA) kit for the M177 platform includes a digital readout for ethanol content and fuel temperature, providing real-time monitoring via the Spool Ethanol Analyzer App on mobile devices. Powered by BLE 4.0 technology, the app connects wirelessly to the ECA module for easy, accurate tracking. The ECA module also provides a 0-5V output for flex-fuel implementation if needed.

Tune Changes Required:

To ensure optimal performance and protect your C63 M177 engine, the upgraded pumps require calibration changes. These changes must be applied before the car is started with the new pumps installed to prevent damage and avoid voiding your warranty. Spool Performance can provide calibration details to your existing tuner and connect you with experienced tuners familiar with the FX-170 fuel pumps.

Custom tuning is necessary to achieve the best results for your specific setup, and Spool Performance is here to assist with any questions your tuner may have.

Low Pressure Fueling Considerations:

For optimal fuel system performance, it’s essential to maintain proper low-pressure fueling. Without adequate low-pressure fuel supply, damage to the high-pressure pump and injectors may occur. Ensure that you upgrade the low-pressure side of your fuel system as necessary to avoid fuel starvation and potential damage to components. We recommend working with a professional to design a balanced fuel system to support high-performance builds.

Vehicle Fitment:

• Mercedes-AMG C63 (2015–2020)
• Powered by the M177 4.0L Biturbo V8 engine
