Description

The Dorch Engineering BMW N55 Stage 1 High-Pressure Fuel Pump (HPFP) is engineered to significantly enhance fuel delivery for N55 engines, supporting up to 650 wheel-horsepower (WHP). This Stage 1 kit offers a 1.221 cc/rev fuel flow and is designed as a direct, plug-and-play replacement for the factory unit, requiring no cutting, bending, or crimping for installation. Importantly, it allows for full control by the DME, preserving the original vehicle's safety features and sophisticated management systems. This high-pressure fuel pump is specifically designed for 2013+ N55 models equipped with the OE Bosch HPFP. It is crucial to note that this kit is NOT COMPATIBLE with 2011-2012 N55 vehicles. The pump is compatible with a range of BMW models including the F87 M2, F20/21 M135i, F22/23 M235i, F30/31/34 335i, F32/33/36 435i, F10/11 535i, F25/26 X3/X4 35i, and F15/16 X5/X6 35i, as well as certain E-chassis variants like the E8X 135i, E9X 335i, E84 X1 35i, and E70/71 X5/X6 35i (all from 2013+ model years as specified).
