Cometic Subaru EJ20 .045in MLS Cylinder Head Gasket - 103mm Bore

When you're rebuilding the top end of your engine, getting the right head gasket is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) head gasket is built for the Subaru EJ20 engine and features a 103mm bore with a thickness of .045 inches. It's designed to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and engine block.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps create a maximum seal without needing additional sealants, and the multi-layer design can handle the shearing forces between aluminum and cast iron blocks. The center layer is stainless steel, and its thickness can be varied to meet different requirements, like the .045 inch thickness on this particular gasket.
