Porsche Engine Camshaft Timing Adjuster - Genuine Porsche 94610505177

Product Information

The engine variable valve timing (VVT) adjuster is a precision component mounted on the camshaft that regulates the timing of valve opening and closing to optimize engine performance. By adjusting camshaft phasing, the VVT adjuster improves power output, fuel efficiency, and emissions control under varying driving conditions. Typically controlled by oil pressure and an electronic solenoid, it plays a critical role in maintaining smooth engine operation and responsiveness.

• Rough idle or reduced engine performance – caused by improper valve timing control.
• Illuminated check engine light (CEL) – often accompanied by diagnostic trouble codes (DTCs) related to camshaft timing.
• Rattling or knocking noise from the engine – a sign of worn or failing adjuster components.

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.
