Spool Performance - G80/G82/G83/F97/F98 S58 Stage 3 Low Pressure Fuel Pump

Spool Performance Stage 3 Low-Pressure Fuel Pump (LPFP) Kit – BMW S58 Platform

Unlock the full potential of your BMW S58-powered vehicle with the Spool Performance Stage 3 LPFP Kit – the ultimate solution for low-side fueling limitations when pushing high horsepower, especially on E85 or ethanol blends.

As high-pressure pump technology continues to evolve, many builds are now maxing out the low-pressure fuel system long before DI components. The Stage 3 LPFP kit is designed to eliminate that bottleneck with a dual pump solution, delivering nearly double the flow of the factory fuel pump and supporting over 1200whp worth of low-pressure fueling.

One pump runs full-time, while the second is activated via a boost-triggered switch, ensuring reliable fuel delivery only when needed – maximizing flow without excess strain or heat during normal driving. This makes it a perfect upgrade for high-power street builds and full-race applications alike.
