G8X/F97/98 S58 BMW Drop in Brushless LPFP upgrade (800WHP+ Capable)

PFS S58 Drop-In LPFP – 800WHP+ Capable

PFS is proud to offer a true drop-in LPFP solution for the G-Series S58 platform, including the F9X X3M and X4M. This pump supports over 800WHP on E85–E98, with even higher power potential on ethanol blends or race gas.

There are no additional pumps, wiring harnesses, or controllers required. Just drop it in and go.

What Sets It Apart

We start with a factory bucket, then modify it extensively to accept our custom PFS brushless fuel pump. The factory wiring is re-terminated using OEM-grade methods — no splices, no shortcuts — just like the factory would.

This is a true drop-in solution:

• Remove your stock unit

• Install the PFS pump

• Plug the factory connector into the new top hat

• Done.

The factory ECU controls everything, and no tuning changes are needed to take full advantage of the upgrade.

How to Order

We offer three options:

New Build
Keep your original pump — we send you a brand-new PFS upgraded unit.

Send Core First
Send us your stock pump first. We’ll send back a PFS-upgraded version once received.

Core Build
We upgrade a PFS-sourced OEM core in good condition with a brand-new brushless pump. Each unit is flow-tested to the same spec as our new builds — just at a lower price.  This is your best value. If they're available, snag one — they go fast.  Quantities limited.

X3M/X4M Owners:
LCI and Pre-LCI vehicles use different top hats. Email us to confirm fitment before ordering.
