Spool Performance AMG GT/GTS/GTC/GTR [M178] Spool FX-350 Upgraded High Pressure Pump Kit

Introducing the Spool Performance FX-350, the ultimate high-pressure fuel pump upgrade designed to exceed the capabilities of the previous FX-200 model. This cutting-edge pump offers superior performance and efficiency, making it an essential upgrade for high-performance applications.

Key Features

• Enhanced Pressure and Flow: The FX-350 delivers fuel at an impressive 35MPa, a significant increase over the 25MPa provided by the FX-200. This enhanced pressure translates into a 40% increase in fuel flow through your injectors, enabling them to provide more fuel before reaching their limits. This is crucial for supporting high-power builds, larger turbos, and higher ethanol blends.

• Improved Fuel Atomization: Higher pressure from the FX-350 results in finer fuel droplets, leading to better atomization. In direct-injection engines, this means more efficient combustion, increased power output, enhanced fuel economy, and reduced emissions.

• High-Quality Components: The FX-350 is engineered with precision to offer unmatched efficiency and reliability, making it a significant upgrade for maximizing engine potential.

Why You Need It

The stock HPFP on the M177 motors is limited in capacity, particularly when tuning for higher performance levels. The FX-350 enhances the fueling capacity by 90%, allowing for more aggressive tuning, larger turbochargers, and higher ethanol concentrations.

What’s Included

• 2 x FX-350 Upgraded High-Pressure Fuel Pumps
• 1 x Ethanol Content Monitor Kit (if option selected) with mobile app
• 1 x Bosch Spec 10-Micron High-Flow Fuel Filter
• Upgraded Fuel Lines: Black nylon-coated, braided steel PTFE core, 100% E85 compatible
• All Necessary Installation Hardware

Spool 10-Micron Filter Unit

The 10-micron filter unit provides superior filtration for the Mercedes market, ensuring no noticeable pressure drop in the low side fuel system. It protects the high-pressure pump and injectors from debris, which is crucial for maintaining performance and reliability.

Spool Ethanol Content Monitor

• Digital Readout: Displays in-tank ethanol content and fuel temperature
• Bluetooth 4.0 Technology: Minimal battery usage with regular Bluetooth functions on your smartphone
• Free Mobile App: Features an Ethanol Mix Calculator to ensure the perfect fuel blend

Are Tune Changes Required?

Yes, calibration changes are required for the upgraded pumps. It is essential to apply these changes before starting the car with the new pumps installed to prevent potential damage and avoid voiding the warranty. Spool Performance can provide calibration details to your existing tuner or connect you with experienced tuners for the FX-350 setup. Custom tuning is necessary to achieve optimal performance based on your specific vehicle setup and conditions.

Low Pressure Fuel Pump Upgrade

Adequate low-pressure fueling is vital for the proper function and durability of high-pressure pumps and injectors. Insufficient low-pressure fueling can damage the pump piston and bore due to inadequate lubrication. Ensure you plan your fuel system build with proper low-pressure upgrades to prevent potential issues and warranty voids.
