Spool Stage 3 Low Pressure Fuel Pump (Built Bucket) - BMW S58

Spool Performance is excited to introduce our Stage 3 Low-Pressure Fuel Pump (LPFP) Kit for the S58 platform . This kit provides a comprehensive solution to low-side fueling limitations by including everything needed to add a secondary boost-activated low-pressure pump. As high-pressure fuel pumps continue to advance and support greater Direct Injection (DI) fueling , stock low-pressure electric pumps have become a bottleneck when pursuing high horsepower—particularly with E85 fuel . Our Stage 3 LPFP Kit addresses this limitation with a twin-pump configuration , activating a secondary pump during boost onset. This setup nearly doubles the flow of the stock pump, providing sufficient fueling to support over 1200whp , regardless of fuel type. Key Features: Twin-Pump Design: Boost-activated secondary pump ensures consistent fuel delivery under demanding conditions.

Fits: BMW S58: M3 (G80/G81), M4 (G82/G83), M2 (G87), X3 M (F97), X4 M (F98)
