Dorch Engineering DS3 High Pressure Fuel Pump (HPFP) - BMW F20 M140i | F22 M240i | F30 340i | F32 440i (B58 Gen1)

The Dorch Engineering DS3 (Dorch Stage 3) is the highest flowing single pump solution for the Gen1 B58, with Dorch's largest bore size to date and around 20% more fuelling than the DS25.

It retains the same reliable OEM drop-in design, with OEM hose routing for zero interference when changing coil packs or spark plugs and an included OEM-quality high pressure line. Combined with Dorch injectors and camshaft upgrades, it opens the door to four-figure direct-injection power.

Please note:

• Software changes are required to run this pump. Bootmod3, MHD and MG Flasher users can simply select the Dorch pump upgrade when flashing; otherwise a custom WinOLS calibration will be needed.
• Please select the option to suit your car. Only suitable for Gen1 B58 vehicles up to the 2019 model year – not compatible with 2020-on B58 vehicles.
