Dorch Engineering DS3 High Pressure Fuel Pump (HPFP) - BMW F20 M135i | F22 M235i | F30 335i | F32 435i | F87 M2 (N55)

The Dorch Engineering DS3 (Dorch Stage 3) is the highest flowing single pump solution for the N55, with Dorch's largest bore size to date and around 20% more fuelling than the DS25.

It is the ideal track-proven upgrade for those who need more than the DS25 can offer without committing to the cost and installation of an N55 Lift Kit combination. As with all Dorch pumps, it drops straight in with full DME control and all factory safety strategies retained.

Please note:

• Software changes are required to run this pump. MHD and Bootmod3 users can simply select the Dorch pump upgrade when flashing; otherwise a custom WinOLS calibration will be needed.
• Only suitable for 2013-on N55 engines with the OE Bosch HPFP – not compatible with 2011–2012 N55 vehicles.
