Spool Performance GLS63 AMG [M177] Spool FX-170 Upgraded High Pressure Pump Kit

Introducing the Spool Performance FX-170, an advanced high-pressure fuel pump designed to elevate the performance of your Mercedes-AMG GLS63 M177. The FX-170 offers improved fuel delivery, making it ideal for high-performance tuning.

What is the FX-170?

The FX-170 is an upgraded high-pressure fuel pump with several enhancements:

• Increased Flow: Featuring a larger bore size compared to the stock pump, the FX-170 provides approximately 50% more flow. This upgrade supports higher ethanol concentrations and larger turbos.

• E85 Compatibility: Fully compatible with E85 fuel, the FX-170 is designed for a plug-and-play installation, eliminating the need for cutting or splicing. It offers a seamless upgrade to meet increased fueling demands.

Why do you need it?

The stock high-pressure fuel pump (HPFP) in the M177 motors has limitations that can restrict performance:

• Enhanced Flow Capacity: The FX-170 adds 50% more flow compared to the stock pump, which helps overcome the limitations of the stock pump. This upgrade allows for running bigger turbos and higher ethanol blends, optimizing engine performance.

What does the kit include?

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

The Spool Ethanol Content Monitor (ECA) features:

• Digital Readout: Displays in-tank ethanol content and fuel temperature.
• Mobile App: Includes the SPOOL Ethanol Content Analyzer app for real-time monitoring.
• BLE 4.0 Technology: Allows connection with standard Bluetooth devices.

Are tune changes required?

Yes, calibration changes are necessary to utilize the upgraded pumps effectively:

• Calibration Requirements: Apply calibration changes before starting the car to avoid potential damage and warranty issues. Spool Performance can assist in providing calibration details to your tuner or help connect you with experienced tuners.

Low Pressure Fuel Pump Upgrade

Proper low-pressure fueling is essential for the durability of high-pressure pumps and injectors in a direct-injection system:

• Importance of Low Pressure Fueling: Inadequate low-pressure fueling can cause damage to the pump piston and bore, potentially voiding warranties. Ensure your fuel system build includes appropriate low-pressure upgrades.
