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 S58 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 S58 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 FX-350 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 FX-350 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 FX-350 HPFP is backed by our lifetime warranty program, a testament to the confidence we have in our products.

Perfect fit for my RAM

Installed both filters on my 2011 RAM 3500 6.7L Cummins and everything fit properly. Nice having both filters in one kit instead of ordering separately.

Convenient and worth it

This kit made the service much easier. Both the oil and fuel filter came together, which saved me from searching for each part individually.
