Spool Performance Stage 3 LPFP – BMW F8x M3 / M4

The Spool Performance Stage 3 LPFP (Low Pressure Fuel Pump) is designed for BMW F8x M3 and M4 models seeking significantly increased power and fuel system capacity. In high-power builds, especially with E85 fuel, the original low-pressure pump often becomes a bottleneck in the fuel system.

The Stage 3 LPFP solves this problem by offering a dual pump solution that elevates fuel flow capacity to an entirely new level.

The system uses two electric fuel pumps:

• one pump operates continuously as normal
• the second pump activates when boost pressure rises

This intelligent solution enables nearly double the fuel flow compared to the standard system, ensuring sufficient fuel supply even for very high power outputs.

The Stage 3 LPFP supports power levels of over 1200 whp, regardless of the fuel used (gasoline, E85, or other high-ethanol blends).

The pump is delivered as a ready plug & play unit that directly replaces the original pump. Installation requires no assembly, modifications, or return of the old pump.
