HKS Subaru FA24 1.2mm Thickness 11.3 CR Grommet Type Head Gasket

This HKS head gasket is built with a 1.2mm thickness and designed for an 11.3:1 compression ratio, making it a solid choice for Subaru FA24 engines. It uses a grommet-type seal, which is a well-built design that helps ensure a strong seal between the cylinder head and the engine block. This type of gasket is often chosen when rebuilding or modifying the top end of the engine, aiming for improved sealing under higher stress conditions.

The grommet seal is a key feature here. It's a flexible ring that surrounds the combustion chamber and coolant passages, providing a more robust barrier against leaks compared to older gasket designs. This updated approach helps maintain consistent clamping force and seals effectively even with the increased pressures and temperatures found in performance applications. The 1.2mm thickness is a specific dimension that affects the compression ratio, and this gasket is engineered to work with an 11.3:1 target, which is a notable increase over stock for many FA24 applications.

When you're working on the FA24 engine, especially if you're looking to maintain or slightly increase compression for better performance, a well-made gasket like this HKS unit is important. It's designed to fit right and provide reliable sealing for the engine's critical combustion areas.
