Cometic Subaru EJ20EN Motor SOHC 16V 93mm .030 inch MLS Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket specifically made for Subaru EJ20EN SOHC 16-valve engines with a 93mm bore. It's sized at .030 inches undersize, meaning it's designed to account for specific engine build requirements where a slightly thinner gasket is needed. MLS gaskets are a popular choice for high-output engines because they offer excellent sealing performance without needing any extra sealants.

Cometic builds these gaskets with 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 tough sealing conditions and different surface finishes. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, like the .036 inch operating thickness you get with this .030 inch gasket. This construction makes them suitable for joining aluminum heads to either aluminum or cast iron blocks, as they can manage the stresses that arise from dissimilar metals.
