Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

FX-180 Uprated Direct Injection Pump for BMW B58 engines in M140i, M240i, 340i and 440i

Unlock reliable fuel delivery for serious tuning with the Spool Performance FX-180. This uprated direct injection pump provides around 80 percent more volume than the standard unit, maintains rock-solid rail pressure on higher ethanol content and is a clean, plug in upgrade with no cutting or splicing. Ideal for M140i, M240i, 340i and 440i owners chasing more power on road or track with hybrid or larger turbochargers and ethanol blends including E50 and E85.

We run the FX-180 on our own B58 builds and on customer cars, and the feedback has been superb. Smooth drivability, consistent high-pressure fueling and the confidence to push further with tuning while keeping OEM-like refinement.

Why choose the FX-180 for your B58

  • Around 80 percent more pump capacity than factory for genuine headroom on tuned setups
  • Ethanol friendly construction for E85 and high ethanol blends when calibrated correctly
  • True plug and play fitment with factory lines and connectors, no wiring cuts or hose modifications
  • Stable rail pressure under load to support bigger turbos and higher boost targets
  • OEM behaviour at idle and cruise, strong high rpm delivery when you need it

Measured flow

Flow rates based on B58 stock cam lift:

  • Stock B58 pump: 0.954 cc per rev
  • FX-180: 1.7 cc per rev

Calibration notes

Tuning is required after installation to scale the pump correctly and to run ethanol content safely. Adjustments are supported by major tuners, and Spool can provide calibration changes on request.
