Spool Performance E63 AMG [M177] Spool FX-170 Upgraded High Pressure Pump Kit

Unlock the full potential of your Mercedes-AMG E63 with the Spool Performance FX-170 Upgraded High Pressure Pump Kit. Designed to enhance fuel delivery and support high-output applications, the FX-170 delivers superior performance and reliability for those pushing their vehicle to the limits.

What is the FX-170?

The FX-170 is a high-performance fuel pump upgrade designed for the Mercedes M177 engine. It features a larger bore size compared to the stock pump, providing approximately 50% more flow. The pump is fully compatible with E85 and offers a plug-and-play installation, eliminating the need for any modifications such as cutting or splicing.

• Enhanced Fuel Flow: Provides 50% more flow compared to stock, supporting higher ethanol concentrations and larger turbos.
• E85 Compatibility: Fully compatible with E85 fuels, ensuring reliable performance under high-output conditions.

Why Do You Need It?

The stock high-pressure fuel pump (HPFP) on the M177 engine can limit performance when tuning for higher outputs. The FX-170 addresses this limitation by increasing the flow capacity, making it possible to run larger turbos and higher ethanol blends without compromising engine performance.

What Does the Kit Include?

• 2 x FX-170 Upgraded High-Pressure Fuel Pumps: For enhanced fuel delivery.
• 1 x Ethanol Content Monitor Kit: Includes mobile app (if selected) for monitoring ethanol content and fuel temperature.
• 1 x Bosch Spec 10-Micron High-Flow Fuel Filter: Ensures clean fuel delivery with minimal pressure drop.
• Upgraded Fuel Lines and Installation Hardware: Includes all necessary components for a complete installation.

Spool 10-Micron Filter Unit

Our 10-micron filter unit offers the highest level of filtration available for the M177 platform without causing noticeable pressure drops. It protects the high-pressure pump and injectors from debris, ensuring optimal performance and longevity.

Spool Ethanol Content Monitor

• Digital Readout: Displays in-tank ethanol content and fuel temperature.
• BLE 4.0 Technology: Low energy consumption with seamless Bluetooth connectivity.
• Ethanol Analyzer App: Free to use, with a built-in ethanol mix calculator for accurate blending.

Are Tune Changes Required?

Yes, the FX-170 pumps require calibration changes to ensure proper functionality and prevent potential damage. It is essential to apply these changes before operating the vehicle with the new pumps installed. Spool Performance can provide calibration details to your tuner or assist in connecting with experienced tuners for optimal performance. Note that custom tuning is necessary for the best results, as Spool Performance does not offer custom tunes but can support your tuner with necessary information.

Low Pressure Fuel Pump Upgrade

Proper low-pressure fueling is crucial for the reliable operation and durability of high-pressure pumps and injectors in a direct injection system. Inadequate low-pressure fueling can cause damage and void warranties. Ensure that your fuel system build includes appropriate low-pressure upgrades to maintain optimal performance.
