Spool FX-400 Gen1 B58 Upgraded High Pressure Pump

Spool Performance is excited to introduce the FX-400, our flagship 200 bar high-pressure fuel pump designed for the BMW B58 engine. This upgraded pump delivers approximately 20% more fuel flow than our industry-leading FX200, making it a game changer for extreme high-performance builds. With the FX400, you can achieve higher horsepower on a direct injection (DI) system, especially when paired with Spool’s IFX150 Gen1 DI injectors. It is fully E85 compatible and is designed for plug-and-play installation with no cutting or splicing required.

The FX400 allows for higher ethanol concentrations and supports larger turbo setups, ensuring you have the fuel delivery needed for peak performance.

Key Features:

• 20% Increased Fuel Flow: Compared to the FX200, providing superior fuel delivery for high-performance builds.
• 200 Bar High Pressure: Designed to handle the demands of high-performance, high-horsepower applications.
• E85 Compatible: Ready for ethanol-blended fuels to support your build's fuel requirements.
• Plug-and-Play Installation: No cutting or splicing needed for installation.
• Perfect for Larger Turbos: Ensures proper fueling for bigger turbo setups and higher ethanol concentrations.

Tuning and Calibration:

Tune changes are required to run the FX400. It's essential to apply these calibration changes before starting the car with the upgraded pump installed to avoid damage and voiding the warranty. Spool Performance provides calibration support for tuners and helps connect customers with experienced tuners if necessary.

Low Pressure Fuel Pump Considerations:

Proper low-pressure fueling is crucial for the longevity and performance of the high-pressure fuel pump and injectors in a DI system. Insufficient low-pressure fueling can cause damage to the pump piston and bore due to lubrication failure, and such damage can void the warranty. Ensure your build includes an adequate low-pressure fuel pump upgrade.
