Unlock the full performance potential of your FXX N55-powered BMW with the Spool Performance Stage 3 LPFP—the ultimate low-pressure fuel solution for high-horsepower builds. Designed to eliminate the bottleneck in the fuel delivery system, this pump ensures consistent low-side fueling, even when running E85 or pushing past 1200whp.

This system ensures stable fuel pressure and flow for aggressive power builds while remaining fully E85 compatible. Best of all, this is a complete drop-in replacement—no need to turn a screw or return a core.

Important Note:

DISCLAIMER: Connector melting on the primary pump is a known result of overdriving the EKP (fuel pump control module) beyond safe limits, especially when tuning aggressively. This is not considered a product defect and is not covered under warranty. For optimal reliability, avoid excessive EKP load when running a twin-pump system.
