Spool Performance C63 AMG [M177] Spool FX-170 Upgraded High Pressure Pump Kit

Maximize the performance of your Mercedes-AMG C63 with the Spool FX-170 Upgraded High Pressure Fuel Pump (HPFP) Kit. Designed for the M177 engine platform, this high-performance fuel pump delivers approximately 50% more flow than the stock HPFP, making it an essential upgrade for those seeking to push the limits of their AMG’s output, especially when running E85 fuel or larger turbo applications.

Why Upgrade to the FX-170?
The factory HPFP on the M177 engine is limited in fuel delivery capacity, especially as you tune the motor for higher power levels or run ethanol-based fuels. The FX-170 solves this problem by increasing the bore size of the pump, enabling significantly greater fuel flow. This allows for higher ethanol concentrations and better support for big turbo setups, making it a critical upgrade for enthusiasts chasing big power numbers.

Key Features:

• 50% More Flow: The FX-170 provides 50% more flow compared to the stock pump, ensuring that your engine gets the fuel it needs for high-power applications.
• E85 Compatibility: Fully compatible with ethanol-based fuels, the FX-170 allows you to run higher ethanol concentrations for better performance.
• Plug and Play Installation: No cutting or splicing required. The kit is a direct-fit upgrade designed for easy installation.

What’s Included in the Kit:

• 2 x FX-170 Upgraded High-Pressure Fuel Pumps: Increase fuel flow for high-output builds.
• 1 x Ethanol Content Monitor Kit (if selected): Includes mobile apps for real-time monitoring of ethanol content and fuel temperature.
• 1 x Bosch 10-Micron High Flow Fuel Filter: Protects the fuel system with the best filtration available for the M177 platform.
• Upgraded Fuel Lines and Install Hardware: 100% E85 compatible, durable braided steel fuel lines ensure reliable performance.

Advanced Filtration & Ethanol Monitoring:
The kit includes a 10-micron filter that offers superior filtration to protect your high-pressure fuel pump and injectors from debris, ensuring long-lasting performance. Additionally, the optional Ethanol Content Analyzer (ECA) provides a digital readout of in-tank ethanol content and fuel temperature via the SPOOL app on mobile and watch devices. This system also supports BLE 4.0, so you can stay connected to the ECA module while using other Bluetooth devices.

Tune Adjustments Required:
This upgraded pump kit does require calibration changes to work properly. It is important to update your tune before starting the vehicle after installation to avoid any potential damage. Spool Performance offers calibration support and can help connect you with experienced tuners familiar with this upgrade. Although Spool Performance does not provide custom tuning, they offer assistance to your tuner for achieving the best results.

Low Pressure Fuel System Considerations:
To maintain the health and longevity of your high-pressure fuel pump, ensure that the low-pressure side of your fuel system is properly upgraded. Low-pressure fuel starvation can cause damage to the HPFP, and this type of damage is detectable and can void warranties. Proper low-pressure fueling upgrades are essential for optimal performance and durability.
