Spool Performance is proud to introduce our latest and greatest high-pressure fuel pump capable of delivering 50% more fuel than OEM pumps for the S63 platform. Our latest innovation is designed to deliver fuel at a groundbreaking 390 bar (39Mpa/5600psi), ensuring your vehicle has the fueling capacity it needs to perform at its best.

Engineered Excellence The FX-350 pump is a masterpiece of precision engineering, featuring robust stainless-steel construction with a high-tolerance, DLC-coated piston and bore. This pump isn’t just about higher pressure; it’s about delivering consistent high output volume, reliably engineered to outperform OEM pumps at 390 bar pressure.

Revolutionary Design Tailored specifically for the high-revving S63 dual-pump design, the FX-350 is a testament to bespoke engineering. E85 compatibility is a standard feature, enabling you to fully leverage the benefits of E85 fuel for uncompromised performance. As a centerpiece for big power DI-only systems on Gen2 BMW DI engines, the FX350 pump, when paired with our IFX350 Gen2 DI injectors, forms a powerful duo that solves the high-pressure fueling puzzle with ease.

Plug and Play Convenience Ease of installation is a promise. The FX350 arrives as a complete kit, including all necessary lines and hardware for a seamless fit. Compatibility is assured across all platforms we support.

Unmatched Reliability At Spool Performance, quality is more than a buzzword—it's our pledge. The FX350 HPFP is backed by our lifetime warranty program, a testament to the confidence we have in our products.

Note: An upgraded low-pressure fuel pump is recommended to ensure the FX-350 operates within its optimal range. Our lifetime warranty underlines our quality, yet it's essential to avoid cavitation-induced damage, which is not covered as it is not a design or manufacturing-related failure mode.

Tuning changes are required to run the fuel pumps, and we’re in the process of adding these to the different flashing platforms. Meanwhile our team can assist with adding the required changes to tune files.
