MAHLE Spark Plug Tube Seal

The MAHLE Spark Plug Tube Seal (also called a spark plug well seal or spark plug tube gasket) is a sealing component for the spark plug tube opening in the valve cover. It helps keep engine oil out of the spark plug well and keeps dirt and moisture out of the area around the plugs and ignition coils.

Key Features:

• Seals the spark plug tube where it passes through the valve cover
• Helps prevent oil leaks into the spark plug well, which can cause misfires and fouled plugs or coils
• Made to OE-style specifications, so it fits and seals reliably
• Made from durable sealing material that resists heat, oil and engine vibration
• Designed as a replacement when the valve cover is removed or when oil seeps around the plug wells

MAHLE is a global OE supplier of engine sealing and gasket products. Replacing worn tube seals when you service the valve cover gasket helps restore proper sealing and keeps the ignition system clean and dry. Select the correct part number from the variants listed on this page.
