About this part

Product Details

Cometic Gasket is a well-known name for creating dependable sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example of their work. It's designed to handle the demands of high-output engines, offering a robust seal without needing extra sealants. This gasket is a solid choice for rebuilding or replacing the head gaskets on a variety of Subaru models, including the Forester, Impreza, and Legacy, as well as the Saab 9-2X and Subaru Baja. It's built to work with both aluminum and cast iron blocks, and it can handle the stresses that come from mating different metal types.

What makes this gasket stand out is its construction. It's made from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in tough sealing environments. The center layer is stainless steel and can be varied to achieve different thicknesses; in this case, it's set to a compressed operating thickness of 0.036 inches, with a bore size of 101mm and an overall thickness of .080 inches. This design helps ensure a reliable seal even under significant pressure.
