Audi Spark Plug Tube Seal - Genuine Audi 0P2103649E

Product Information

A spark plug tube seal is a rubber or silicone gasket that sits at the top of the spark plug tube, preventing engine oil from leaking into the tube and onto the spark plugs. It ensures a clean, dry environment for proper ignition and helps maintain engine performance and reliability. Over time, the seal can harden or crack due to heat and oil exposure, requiring replacement to prevent misfires and oil contamination.

• Oil leaks into spark plug wells, causing fouled or misfiring plugs.
• Check Engine Light illumination, often triggered by misfires.
• Visible oil seepage around the valve cover or spark plug tube area.

About Genuine Audi

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

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