Cometic 2012+ Honda K20Z7 SI 87mm Bore .040in MLS Head Gasket

If you're working on the top end of your 2012-2015 Honda Civic, especially the K20Z7 SI engine, this Cometic Multi-Layer Steel (MLS) head gasket is what you need. It's built to handle the demands of high-output engines, ensuring a solid seal between your cylinder head and engine block without needing extra sealants.

This gasket is constructed from multiple layers of stainless steel, which gives it 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, making it suitable for various sealing conditions and surface finishes. The center layer is uncoated stainless steel and can be varied in thickness; in this case, it's set at .040 inches with an 87mm bore to match your specific engine requirements. This design is effective for sealing between aluminum heads and either aluminum or cast iron blocks, as it can manage the shearing forces that occur between different metals.
