High-Pressure Fuel Pump for B46D/B58/S58 Engines

The Bosch High-Pressure Fuel Pump (HPFP), listed as part number 0261520520, is a brand-new OEM component that replaces BMW part number 13518631642. It is specifically designed for B46D, B58C, B58D, and S58 engines found in various BMW models, including 30i/40i and M drivetrains, as well as some BMW-powered A90/GR Supra models. This HPFP represents an upgrade over the stock HDP-5-EVO pump, featuring a higher displacement of 1.178 cc/rev and capable of up to 350 bar of pressure, compared to the HDP-5-EVO's 0.954 cc/rev and 250 bar. This makes it a suitable plug-and-play solution for tuned Gen 1 B48/B58 applications requiring increased fueling for tuning purposes and enhanced performance. Installation on a Gen 1 B58/B48 requires rotating the connector housing for the fuel quantity control valve, a straightforward process. Alternatively, an extension harness can be used. Tuning is necessary to achieve the maximum performance gains from this pump. The pump is manufactured in Germany and is considered a performance quality part with a two-year warranty.
