High-Pressure Fuel Pump

The Bosch High Pressure Fuel Pump (HPFP) is an OE-quality replacement part designed specifically for modern gasoline direct injection (GDI) engines. This critical component, driven by the engine's camshaft, operates by boosting fuel pressure to extremely high levels, enabling precise fuel delivery directly into the combustion chamber. This process leads to improved fuel atomization, enhanced efficiency, and higher power output. Common failures of this high-pressure fuel pump can lead to check engine lights and limp mode conditions. Symptoms of failure may include engine performance problems such as hard starting, hesitation, misfires, or loss of power under load. Additionally, fuel-related issues like lean/rich codes or reduced fuel economy, as well as noises like ticking or whining from the pump, or visible fuel leakage, can indicate a problem. This HPFP is manufactured in Germany and is built to meet the rigorous standards expected of OE components. It is designed to replace BMW part number 13518631642 and is compatible with various BMW models equipped with B46D, B58C, B58D, and S58 engines, including many 30i, 40i, and M drivetrains. The fitment list includes numerous BMW 3 Series, X2, X5, X7, and Z4 models from 2019 through 2026, covering various engine configurations and drivetrain types.
