Dorch DS25 High-Pressure Fuel Pump Kit – BMW N55
DESCRIPTION
The Dorch DS25 is a high-pressure fuel pump upgrade for N55 builds that need additional fuelling capacity. The kit retains factory DME control and includes the pump, installation hardware, high-pressure line, low-pressure hose and adapter harness.
Key details
Choose the harness to match the connector fitted to your car. Earlier cars generally use the old-style connector; later cars use the new style. Cars built from December 2013 to June 2014 can have either, so check the connector visually before ordering.
Fitment and installation
For compatible 2013-on N55 cars with the original Bosch high-pressure pump, including M135i, M235i, 335i, 435i and N55 M2 applications. Not compatible with 2011–2012 N55 pump systems. Professional installation and the correct Dorch pump calibration are required.
