About this part

Product Details

When you're rebuilding the top end of your Subaru, getting the cylinder head gasket seated right is crucial for sealing combustion pressure and coolant. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder head and block.

Cometic constructs these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material designed to seal effectively even in harsh conditions and on various surface finishes. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, with this particular gasket having a compressed operating thickness of 0.036 inches. This construction means it doesn't require any additional sealants and is suitable for mating aluminum heads to either aluminum or cast iron blocks, as it can withstand the forces created by dissimilar metals.

This gasket features an 86mm bore and a thickness of 0.092 inches, making it a direct fit for the specified Subaru models. It's a well-built component designed for reliable performance in your engine rebuild.
