BMW High Pressure Fuel Pump Kit - 13517616446KT

Product Information

A direct injection high pressure fuel pump (HPFP) is a critical component in modern gasoline direct injection (GDI) engines. Unlike traditional fuel pumps, it boosts fuel pressure to extremely high levels (often over 2,000 psi) so fuel can be directly injected into the combustion chamber. This enables better fuel atomization, improved efficiency, and higher power output. The HPFP is typically driven by the camshaft and works in tandem with a low-pressure fuel pump. Over time, wear, contamination, or internal failure can lead to drivability issues.

• Engine performance problems – hard starting, hesitation, misfires, or loss of power under load.
• Fuel-related issues – check engine light, lean/rich codes, or reduced fuel economy.
• Noises or leaks – ticking/whining sounds from the pump or visible fuel leakage at the pump area.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
