Spool Performance FX-180 High-pressure fuel pump upgrade


What is the FX-180?

The FX-180 is an upgraded high-pressure fuel pump for the F series N55 and B58 motors. The pump features a bigger bore size than stock that translates into roughly 80% more flow when compared to stock. The pump is 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-180 adds roughly 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.


Are tune changes required?

The upgraded pump does require calibration changes. It is important to apply these changes prior to starting the car with pump installed to avoid any possible damage and void of warranty.
