Federal Mogul ES72393 Spark Plug Tube Seal Set GM 2.8L/3.0L/3.6L V6

The Fel-Pro ES72393 is a Spark Plug Tube Seal Set engineered by Federal Mogul for GM-platform V6 engines. Spark plug tube seals prevent oil from migrating down into the spark plug wells, a common failure point on overhead-cam engines that can cause misfires, foul spark plugs, and contaminate ignition coils. This set restores a leak-free barrier between the valve cover and spark plug tubes.

Key Features:

• Application-specific materials designed for a precise, reliable seal
• Manufactured by Fel-Pro, a Federal Mogul brand trusted by professional technicians
• Sold as a complete set for full service in a single purchase
• Direct-fit replacement requiring no modifications
• Resists heat, oil, and engine fluids for long-lasting durability

This seal set is designed for GM 2.8L, 3.0L, and 3.6L V6 DOHC engines found across a wide range of GM, Cadillac, Buick, Chevrolet, GMC, Saab, Saturn, and Pontiac vehicles. Commonly replaced during valve cover gasket service or when oil in the spark plug wells is diagnosed.
