Spool BMW Gen1 S63 FX-170 Upgraded High Pressure Fuel Pump Kit

What is the FX-170?

The FX-170 is an upgraded high-pressure fuel pump. The pump features a bigger bore size than stock which 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 fuelling for bigger turbos. The FX170 also is capable of running at 25% more operating pressure than stock pumps helping injectors flow more volume of fuel for the same opening time.

Why do you need it

The stock HPFP on the S63 Motors is severely limited in capacity when trying to tune and raise the output of the motor. The FX-170 adds 50% more flow to the equation and also lets the injectors flow more, raising the fuelling limits on the platform and helping you run bigger turbos and/or higher ethanol concentration blends.
