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. The FX-170 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhy do you need it\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe stock HPFP on the B58 motors is severely limited in capacity when trying to tune and raise the output of the motor.
