Spool Performance AMG E63 [M177] Spool FX-350 Upgraded High Pressure Pump Kit

Elevate your high-performance setup with the Spool Performance FX-350 Upgraded High Pressure Pump Kit, designed specifically for the Mercedes-AMG M177 engine. Building on the success of the FX200, the FX-350 offers significant advancements in pressure and flow, providing a substantial upgrade for high-output and demanding applications.

What is the FX-350?

The FX-350 is a state-of-the-art high-pressure fuel pump engineered to enhance your vehicle's performance by delivering fuel at a remarkable 35Mpa, compared to the 25Mpa of the previous FX200 model. This increased pressure translates into a 40% improvement in fuel flow through the injectors, allowing for greater fuel delivery and supporting higher horsepower setups.

• Enhanced Pressure and Flow: Capable of delivering 35Mpa, the FX-350 ensures 90% more flow than stock, meeting the demands of larger turbos and higher ethanol blends.
• Improved Fuel Atomization: The higher pressure results in finer fuel atomization, leading to more efficient combustion, improved power output, better fuel economy, and reduced emissions.

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-350 addresses these limitations by providing 90% more flow, allowing for increased fueling capacity essential for running bigger turbos and higher ethanol concentrations.

What Does the Kit Include?

• 2 x FX-350 High-Pressure Fuel Pumps: Upgraded for superior performance.
• 1 x Ethanol Content Monitor Kit: Includes mobile app (if selected) for real-time monitoring.
• 1 x Bosch Spec 10-Micron High-Flow Fuel Filter: Ensures clean fuel delivery with minimal pressure drop.
• Upgraded Fuel Lines and Installation Hardware: Black nylon coated, braided steel PTFE core, 100% E85 compatible.

Spool 10-Micron Filter Unit

Our 10-micron filter unit is designed to provide optimal filtration without noticeable pressure drop, protecting your high-pressure pump and injectors from debris and enhancing overall system reliability.

Spool Ethanol Content Monitor

• Digital Readout: Monitors in-tank ethanol content and fuel temperature.
• BLE 4.0 Technology: Ensures low energy consumption while maintaining Bluetooth connectivity for your mobile devices.
• Ethanol Analyzer App: Free of charge, it includes an ethanol mix calculator and allows for accurate blending.

Are Tune Changes Required?

Yes, calibration changes are necessary when installing the upgraded pumps. It’s crucial to make these changes before starting the vehicle to prevent potential damage and warranty issues. Spool Performance can provide calibration details to your tuner or connect you with experienced tuners to ensure optimal performance.

Low Pressure Fuel Pump Upgrade

Proper low-pressure fueling is essential for the effective operation and longevity of high-pressure pumps and injectors in a direct injection system. Ensure your fuel system is equipped with appropriate low-pressure upgrades to prevent damage and maintain warranty coverage.
