Maximize your BMW N20 or N26 engine’s performance potential with the Spool Performance FX-170 Upgraded High Pressure Fuel Pump Kit, a robust fueling solution engineered for enthusiasts demanding more from their builds. Designed for seamless integration, this plug-and-play HPFP upgrade delivers a 50% increase in fuel flow over the factory pump, enabling safe and efficient operation on high-boost applications, ethanol blends, and big turbo setups.

The FX-170’s enlarged bore and advanced internal design allow it to operate at 25% higher pressure than stock, giving your injectors the ability to push more fuel per injection cycle. This added fueling headroom makes it ideal for setups running E85, hybrid or upgraded turbos, or aggressive performance tunes. With full E85 compatibility, it enables greater flexibility in tuning while preserving engine reliability under increased demand.

The FX-170 is a true plug-and-play upgrade—no cutting, wiring, or modifications required. Installation is straightforward with all necessary hardware and fuel lines included in the kit, making it an excellent solution for those looking to elevate performance while maintaining OEM-level integration.

Tune Requirements: The FX-170 requires ECU calibration adjustments before the vehicle is started with the pump installed. Spool Performance can provide calibration data to your existing tuner and can also connect you with experienced tuning professionals familiar with the platform. While Spool does not offer tuning services directly, they provide full support to help your tuner optimize your setup.

LPFP Upgrade Required: For optimal performance and to prevent damage, a low-pressure fuel pump upgrade is essential. In DI systems, low-pressure fuel not only supplies the HPFP but also provides lubrication to its internal components. Operating the FX-170 without adequate LPFP support can result in internal wear or failure, which is detectable and not covered under warranty. Be sure to plan your fuel system upgrade holistically to ensure long-term success.
