Mercedes Spark Plug Tube Seal - AJUSA 1110160721

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.
