Spool Performance BMW Gen2 B58 FX-350 Upgraded High Pressure Pump

Spool Performance introduces the FX-350, an upgraded high-pressure fuel pump for the BMW Gen2 B58 engine platform, capable of delivering fuel at a remarkable 350 bar (5000 psi). This pump is crafted from stainless steel and features a high-tolerance DLC-coated piston and bore, ensuring durability and superior performance. With a similar flow volume to the FX200 but at much higher pressure, the FX-350 is designed to handle increased power demands.

Coupled with Spool Performance’s IFX150 Gen2 DI injectors, the FX-350 completes the high-pressure fueling system required for DI-only big power builds. It also supports plug-and-play installation with all necessary hardware included, making it an excellent choice for enhancing your BMW’s fuel system.
