Spool FX-350 HPFP fuel pump, BMW B58 Gen2 / TU engines

Spool Performance’s Revolutionary High-Pressure Fuel Pump for Gen2 B58. Embark on a new era of Gen2 B58 performance with Spool Performance’s latest triumph – FX350 is capable of seamlessly delivering good amount of fuel at 350 bar/35Mpa/5000psi. Crafted with precision, the pump features a robust stainless-steel construction, housing a high-tolerance DLC coated piston and bore. What sets this pump apart is its unique engineering, designed to match the volume output of our renowned FX200 pumps but at an unparalleled 350 bar pressure. Elevating the output even further is our Spool Performance Gen2 High lift cam lobe mod, ensuring an extraordinary performance when needed.

We recommend the optional Spool fuel filter 10micron, to ensure a reliable operation of your fuel system under harsh conditions.

The specially engineered plunger springs not only complement the cam lobe mod but also effectively mitigate float at high rpms, even with the increased lift from the cam modification.

The FX-350, when paired with our IFX150 Gen2 DI injectors, emerges as the long-awaited missing link for achieving substantial power gains through DI-only applications on the Gen2 BMW high-pressure fuel system.

The FX-350 promises a hassle-free installation on all supported platforms, providing all the necessary lines and hardware for a clean setup. As always, Spool Performance stands firmly behind the excellence of our products, and the FX-350 is no exception, qualifying for our lifetime warranty program.

To fully unlock the potential of the FX-350, ECU tuning changes are imperative. We are diligently working on integrating these changes into various flashing platforms. In the meantime, our dedicated team is ready to assist you in seamlessly incorporating the required adjustments into your tune files. Elevate your driving experience with Spool Performance’s FX-350 – where power meets precision.

Note: Proper low pressure fueling is critical to proper normal functioning of the HPFP. Although our pumps are covered by our lifetime warranty program as usual, any damage due to cavitation induced damages to the piston/bore would be excluded from coverage. Please make sure you are running an upgraded low pressure fuel pump to ensure adequate pressure delivery to the FX-350 pump.
