Spool Performance Stage 3 Plus Low Side Fuel Pump for BMW E60 535i and 535xi N54

Unlock reliable fueling for serious power with this high-flow in-tank pump assembly engineered for the 3.0 twin-turbo N54 5 Series. Designed as a direct-fit replacement for the factory lift pump, this Stage 3 Plus solution delivers the headroom needed for aggressive tunes, hybrid or single turbo builds, and ethanol blends, while keeping factory-style drivability and quiet operation. It is fully ethanol safe, supports flex-fuel setups, and is rated to feed builds up to 1000 bhp when properly matched with the rest of your fuel system and calibration.

We have fitted this kit on customer BMW E60 projects at MJ Modifications and the results have been excellent. Stable low-side pressure, smooth hot and cold starts, and consistent fuel delivery on E blends make it a go-to choice for N54 owners aiming for dependable performance on the road and track.
