Spool Performance FX-150 and FX-180 High-pressure fuel pump upgrade

Spool Performance is really excited to introduce their latest product offering to the F-series and late E series N55 community, the Fx-150 and Fx-180 high-pressure fuel pump upgrades. 

What are the FX-150 and FX-180?

The FX-150 and FX-180 are upgraded high-pressure fuel pumps for the F series N55 and N55 motors. The pump features a bigger bore size than stock that translates into roughly 50-80% more flow when compared to stock. The pumps are completely E85 compatible and fully plug and play with no cutting or splicing of any kind required. The added flow will let you run much higher ethanol concentrations and also allow fueling for bigger turbos.

Why do you need it

The stock HPFP on the F series and late E series N55 motor is severely limited in capacity when trying to tune and raise the output of the motor. The FX-150 and FX-180 add 50-80% more flow to the equation, raising the fueling limits on the platform and helping you run bigger turbos and/or higher ethanol concentration blends.


Tune changes

Tune changes are required to use the FX-150 system. The changes are available with all major tuners and Spool performance will provide the necessary calibration changes needed for the same upon request.
