FX-150 Uprated Injection Pump for BMW B58 - M140i, M240i, 340i, 440i

Give your B58-powered BMW the fuel system headroom it deserves. The Spool Performance FX-150 is a direct-fit, bolt-on injection pump that delivers roughly fifty percent more volume than the factory unit, unlocking reliable fueling for tuned setups, hybrid turbo builds and ethanol blends. If you are chasing stable rail pressure at higher boost or running E blends, this is the go-to B58 fuel system upgrade in the UK.

We have fitted and run the FX-150 on our own cars and for many customers. Feedback has been excellent - smooth drivability, strong pressure control under load and the confidence to push power safely with the right calibration.

Key reasons enthusiasts choose the FX-150

  • Approximately 50 percent more delivery versus the stock B58 pump - serious headroom for power increases
  • Measured output: 1.43 cc per revolution vs OEM 0.954 cc per revolution based on standard B58 cam lift
  • Ethanol-ready - supports E blends including E85 when paired with suitable tuning
  • True drop-in installation - no cutting, no splicing, retains factory lines and connectors
  • Maintains high fuel rail pressure on big boost and larger turbo applications
  • Proven on B58 platforms with consistently positive owner reviews and real-world results
