High Pressure Fuel Pump

The Bosch High Pressure Fuel Pump (MPN: 948110316HX) is engineered for specific Porsche applications, serving as a direct replacement for OE part number 948110316HX. This high-pressure fuel pump is designed to deliver optimal performance for Porsche Cayenne 92A models from 2008-2012 and Panamera 970 models from 2009-2012, specifically those equipped with the 4.8L V8 M48.05/M48.06 naturally aspirated engines (Engine Codes CJLA/CJLB). This fuel pump is constructed with innovation and durability in mind. It features a forged aluminum housing paired with nitride-coated steel plungers, providing resistance to continuous operation at temperatures up to 150°C (302°F). This robust build ensures longevity and reliability under demanding conditions. Its high-pressure performance capabilities ensure it maintains 1,600-2,000 PSI fuel rail pressure, which is critical for achieving optimized combustion efficiency in naturally aspirated engines. This component supports both factory-standard replacement needs and can accommodate performance tuning upgrades.
