What is a stopper head gasket?

A stopper head gasket uses a raised bead around critical sealing areas like the combustion chamber. This bead compresses when the cylinder head is torqued down, creating a very strong seal that can handle higher pressures and temperatures effectively.

Does this gasket include new head bolts?

This product is for the head gasket only. It is recommended to use new head bolts when replacing a head gasket, as they are often torque-to-yield and should not be reused. Please check the product details or contact us to see if a head bolt kit is available separately.

What is the benefit of the 8.3:1 compression ratio?

The 8.3:1 compression ratio is a specific target for this gasket, which can be beneficial for engine tuning and performance. It helps balance power output with the engine's ability to handle boost or specific fuel types, especially in modified 4G63BT engines.

Product Details

This HKS stopper head gasket is 1.6mm thick and designed for an 86mm bore, with a compression ratio of 8.3:1. It's built specifically for the 4G63BT engine found in the 1989-1999 Eagle Talon TSI models. A well-built head gasket is crucial for sealing the combustion chamber, preventing coolant and oil leaks, and maintaining proper compression. This gasket uses a stopper design, which is a robust method for sealing the cylinder head to the engine block, especially important when dealing with higher performance applications or when the engine has been rebuilt.

The 1.6mm thickness is a specific dimension that affects the compression ratio, and HKS has engineered this gasket to achieve a target of 8.3:1 compression for the 4G63BT. This means it's a solid option if you're looking to maintain or slightly adjust your engine's compression for improved performance or to compensate for modifications. The stopper design typically involves a raised bead around the combustion chamber and coolant/oil passages that compresses to form a tight seal, offering strong sealing performance under pressure.

When installing a head gasket, it's always recommended to follow the manufacturer's specific torque sequence and specifications to ensure a proper seal and prevent future issues. This HKS gasket is a direct replacement part designed to fit the specified engine and bore size, making it a reliable choice for your Talon TSI.
