Cometic 2012+ Honda K20Z7 SI 87mm Bore .036in MLS Head Gasket

If you're rebuilding the top end of your 2012-2015 Honda Civic SI, a solid head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of high-output engines, ensuring a dependable seal between your cylinder head and block without needing extra sealants.

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 construction is ideal for mating aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals. The center layer is stainless steel, and its thickness is varied to achieve the specific compressed operating thickness of 0.036 inches, with an 87mm bore designed for your K20Z7 engine.
