About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with an 87mm bore and a compressed thickness of .066 inches, making it a solid choice for your 2012-2015 Honda Civic SI or other compatible K-series engine rebuild. MLS gaskets are known for their strength and ability to handle the demands of high-output engines without needing additional sealants.

The construction features 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 degrees Fahrenheit. This combination ensures a reliable seal between your aluminum heads and either aluminum or cast iron blocks, effectively managing the shearing forces that can occur between dissimilar metals. The center shim layer is stainless steel and can be varied to achieve different thickness requirements, like the .066 inch specification on this particular gasket.
