Dorch Engineering stage 2 high pressure fuel pump N55 F87 M2 F2x F3x BMW

This is a complete plug-and-play kit of the high pressure fuel pump to support up to 550 hp (this number can vary greatly depending on the tuning measure and the ethanol mixture). It is not cut, not bent, not squeezed, etc. This fuel pump is still controlled by the DME, just like the OEM pump. All safety features of the standard DME are retained.
