Volkswagen Engine Cylinder Head - Genuine VW 06L103064S

Product Information

An Engine Cylinder Head is a major engine component that sits on top of the engine block, sealing the combustion chambers with the help of a head gasket. It houses critical parts like the intake and exhaust valves, spark plugs (in gasoline engines), fuel injectors (in some designs), and sometimes the camshafts.

Functions

• Seals the combustion chamber: Works with the head gasket to maintain compression and contain combustion gases.
• Airflow management: Controls intake of the air-fuel mixture and exhaust of burnt gases through valves.
• Houses components: Provides mounting for valves, valve springs, rocker arms, injectors, and spark plugs.
• Cooling & lubrication: Contains passages for coolant and oil to regulate temperature and lubricate moving parts.

• Overheating engine – coolant leaks or blocked passages cause heat buildup.
• Loss of power / misfires – due to poor sealing or damaged valves.
• White smoke from exhaust – coolant leaking into the combustion chamber.
• Oil contamination ("milky oil") – coolant mixing with engine oil inside the head.
• Coolant loss with no visible leak – internal leakage through cracks or warpage.

About Genuine VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

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

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly 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.
