A-Premium APHFP057 Direct Injection High Pressure Fuel Pump for BMW N63 S63 4.4L V8

The A-Premium APHFP057 is a direct-fit, high-pressure fuel pump (HPFP) engineered as an OE-quality replacement for BMW vehicles equipped with the N63 and S63 4.4L V8 turbocharged engines. Designed to meet or exceed OEM specifications, this mechanical pump mounts directly to the engine and restores proper fuel system operation, replacing BMW OEM part numbers 13518604232 and 13517599865, as well as cross-reference number HM10083.

As a critical component of the direct injection fuel system, the high-pressure fuel pump is responsible for generating the sustained elevated fuel pressure — typically in the range of 2,000–3,000 psi — required for precise fuel atomization and direct injection into the combustion chambers. A worn or failing HPFP can cause hard starts, rough idle, reduced power output, engine misfires, and illumination of the check engine light.
