Spool Performance FX-200 High-Pressure Fuel Pump — B58 Gen1 (F-Chassis)

$2,205.00

Spool Performance FX-200 high-pressure fuel pump for the Gen1 B58 — the direct-injection pump that clears the Stage 2/3 fueling ceiling. The factory DI pump runs out of volume as boost and ethanol climb, and the tune starts trimming power to hold rail pressure. The FX-200 roughly doubles stock flow, so fuel stops being the limit.

What it is

A direct, plug-and-play replacement for the OEM high-pressure (direct-injection) pump — about twice stock flow, E85-compatible. A matching calibration is loaded before first start.

Where it fits in the build

High-pressure (DI) side; pair it with an upgraded low-pressure in-tank pump on a Stage 3 build. We tune the engine to the fuel system.

Options

Spool offers a wireless ethanol-content analyzer, a 10-micron inline filter, and a stainless high-pressure line as add-ons — tell us if you want them specced in.

Fitment

Gen1 B58 (F-chassis) — M240i (F22/F23), 340i (F30/F31/F34), 440i (F32/F33/F36), 540i (F10). Confirm your chassis in the selector.

What this is

A Part Recalibration is one focused revision built around the part you just bought. We take logs on your car as it runs now, on your current tune, then make a single full revision so this specific part delivers what it should. Hardware only does its job with a calibration shaped around it.

We bundle that tuning with the part right here, whatever brand the hardware is. If you want a fresh start across all your hardware, a Full Tune is the step up: a new base map, three revisions, and a written report.

This is a bootmod3 calibration. We tune through your own active BM3 license, so you'll need bootmod3 active on your car to load it.

Ships from Boca Raton, FL.

Step up to a Full Tune?

You've added a Part Recalibration to more than one part. At that point a complete tune does more for you: a Full Tune lays down a fresh base map and three revisions so all of your new hardware is dialed in together, with a written report at the end. We can roll your recalibrations into one Full Tune for $395 — below our standalone Full Tune, which starts at $495 for a four-cylinder and $595 for a six.

The Full Tune is a bootmod3 calibration — it loads through your active BM3 license, the same one you confirmed for the recalibration.
WHY WE SHIP SPOOL PERFORMANCE
Spool Performance builds high-pressure fuel pumps for the builds that have outrun what the factory pump can flow. On a big-power direct-injection BMW, fuel supply is often the actual ceiling, and the engine will pull rail pressure long before it runs out of airflow. We ship Spool because their HPFP upgrades are aimed squarely at that ceiling, restoring the supply margin a high-output calibration depends on. This is upper-end fueling hardware — the part you add when the dyno shows the pump, not the turbo, is what is holding the number back.
