Dorch DS25 High-Pressure Fuel Pump Kit – BMW B58 Gen 1
DESCRIPTION
A dedicated high-pressure fuel pump upgrade for first-generation B58 builds. The Dorch DS25 retains factory DME control and is supplied as an installation kit with a matching high-pressure line and vehicle-specific connections.
Key details
Select the 1–4 Series, 5–7 Series or X3/X4 installation version to match the car. These are different kit configurations, not different engine generations.
Fitment and installation
For B58 Gen 1 engines only, including M140i, M240i, 340i and 440i. Confirm engine generation and chassis before ordering; later B58 Gen 2 cars require a different pump kit. Professional installation and the correct Dorch software calibration are required.
DISCLAIMER
Where applicable, the use of de-cats, sports cats and removing OPF/GPF systems is for off-road/motorsport use only. Using these parts may prevent your vehicle from passing an MOT test. Only EC type-approved components are legal and fit for road use.
