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 utilize the upgrade, although you may need to reset your control module for best results. advantage of the upgrade.
