Dorch DS3 High-Pressure Fuel Pump — BMW N55
DESCRIPTION
The Dorch DS3 high-pressure fuel-pump kit provides additional fuelling capacity for supported BMW N55 applications. Choose the harness that matches the connector on your car.
Key details
Old Style (Pre-12/2013) and New Style (12/2013+) refer to the electrical connector. The date split is a guide: some December 2013–June 2014 cars retain the older connector. Check the actual connector against Dorch’s harness identification guide before ordering; do not rely on registration date alone.
Fitment
For N55 BMWs with the factory Bosch high-pressure pump, including F87 M2, F20/F21 M135i, F22/F23 M235i, F30/F31/F34 335i and F32/F33/F36 435i. E-series 135i/335i and F10/F11 535i applications require a confirmed 2013-on Bosch installation. Not compatible with 2011–2012 N55 cars.
Installation
Compatible ECU calibration and professional installation are required. Confirm the existing pump and electrical connector before purchase. Performance depends on the complete fuel system, fuel and calibration.
