Porsche Wheel Valve Stem Set - Genuine Porsche 00004460100

Product Information

A Tire Pressure Monitoring System (TPMS) sensor is an electronic device mounted inside each wheel that measures tire air pressure and transmits the data to the vehicle’s onboard computer. Its primary purpose is to alert the driver when tire pressure falls below the recommended level, helping maintain safety, fuel efficiency, and even tire wear. A properly functioning TPMS sensor ensures optimal vehicle handling and reduces the risk of tire-related failures.

• TPMS warning light illuminated on the dashboard, even when tires are properly inflated.
• Inaccurate or no pressure readings displayed for one or more tires.
• Intermittent alerts or signal loss, often caused by a failing sensor battery.

About Genuine Porsche

The original parts used by Porsche to build your car are available as replacement parts under the “Genuine Porsche” brand. Manufactured under the direction of Porsche, expect excellent quality and a premium price since these parts are exclusively available through the Porsche Dealership network.

You may not realize this, but the parts that make up your Porsche are not necessarily manufactured by Porsche. No cause for concern, as Porsche designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Porsche 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 Porsche parts box and find an OEM branded part inside, simply with the addition of a Porsche 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.
