SPOOL PERFORMANCE FX-350 UPGRADED HIGH PRESSURE FUEL PUMPS [S63 GEN2]

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.
