High Pressure Fuel Pump. 

The BOSCH High Pressure Fuel Pump is a premium OEM-quality fuel system component manufactured by Bosch, engineered to supply the high fuel pressures required by modern direct injection engines. The pump draws fuel from the low-pressure fuel system and compresses it before delivering it to the fuel rail, ensuring precise fuel atomisation and injection timing for optimum combustion efficiency.

Fits:

• Porsche 958 Cayenne S V8 4.2L Diesel (382Hp) 2010-17
