Spool FX-350 Upgraded High Pressure Pump Kit [M276]

Introducing the Spool Performance FX-350, the pinnacle of high-pressure fuel pump technology. Designed to surpass our previous FX-200 model, the FX-350 delivers exceptional performance and efficiency, making it a top choice for high-performance applications.

Key Features

• Enhanced Pressure and Flow: The FX-350 is engineered to deliver fuel at an impressive 35 MPa, a significant upgrade from the 25 MPa of the FX-200. This increase in pressure results in a 40% higher flow rate through the injectors, allowing more fuel to be available for combustion. This enhancement is crucial for applications requiring increased power and efficiency.

• Improved Fuel Atomization: The higher pressure of the FX-350 improves fuel atomization, creating finer fuel droplets for more efficient combustion. This leads to better mixing of fuel and air, resulting in increased power output, improved fuel economy, and reduced emissions.

• 90% More Flow: The FX-350 adds 90% more flow compared to stock pumps, helping you achieve higher performance levels, support bigger turbos, and run higher ethanol concentration blends.

Why You Need It

The stock high-pressure fuel pump (HPFP) on the M276 motors can be limiting when tuning and increasing motor output. The FX-350 addresses this by significantly increasing the fueling capacity, allowing for more aggressive tuning and performance modifications.

• Bluetooth 4.0 Technology: Provides low energy consumption while allowing regular Bluetooth functionality
• Free Mobile App: Includes an Ethanol Mix Calculator for accurate fuel blending

Are Tune Changes Required?

Yes, calibration changes are necessary when installing the FX-350. Applying these changes before starting the car is crucial to avoid potential damage and warranty issues. Spool Performance can provide calibration details to your existing tuner or help connect you with experienced tuners. Custom tuning is required to maximize the FX-350's performance for your specific vehicle setup and conditions.

Low Pressure Fuel Pump Upgrade

Proper low-pressure fueling is essential for the durability and proper function of high-pressure pumps and injectors. Inadequate low-pressure fueling can cause damage and void warranties. Ensure your fuel system build includes appropriate low-pressure upgrades to prevent potential issues.
