Spool Performance proudly introduces the FX-350, a cutting-edge high-pressure fuel pump designed for the BMW S63 Gen2 platform.

Whether you're chasing maximum horsepower or optimizing for E85, this pump provides the performance and reliability you need for high-powered builds.

Engineered Excellence

The FX-350 features precision-engineered stainless-steel construction, with a high-tolerance DLC-coated piston and bore for consistent, high-output volume. Tailored specifically for the dual-pump design of the S63 engine, it’s a game-changer for high-revving applications. Designed to be E85-compatible, the FX-350 is the perfect solution for Gen2 BMW engines utilizing direct injection.

Revolutionary Design

The FX-350 is optimized for big-power DI-only setups, working seamlessly with Spool Performance's IFX350 Gen2 DI injectors to complete the high-pressure fueling solution.

Unmatched Reliability

Backed by Spool Performance's lifetime warranty, the FX-350 delivers unmatched durability and performance. While the warranty covers manufacturing defects, please ensure that the pump is paired with an upgraded low-pressure fuel pump to avoid cavitation-induced damage, which is not covered under warranty.
