Spool Performance N55 upgraded high pressure fuel pumps FX-150

Oct 21, 2018
Spool Performance is really excited to introduce our latest product offering to the F-series and late E series N55 community, the Fx-150 high-pressure fuel pump upgrade. We have been testing this for almost a year now and here it is finally!!


What is the FX-150?
The FX-150 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 50% 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-150 adds 50% 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.

Very nice! what is the price for the FX-180? Just curious because another company has a similar flowing one with apparently life time warranty (that's what theyre saying) for only $1700.

How do we determine if we have a late N55? I'm guessing my 2011 N55 E90 (build date 01/2011) is an early build date?
So any N55 with a build date in early 2011 has the N54 style HPFP. If you're looking to upgrade that then you would need to look into the Helix overdrive unit. You can always contact us before purchasing a product and we will make sure you grab the right one for you car
