Cometic Honda JNC1 .027in HP Cylinder Head Gasket - 92mm Bore

If you're working on the top end of your 2017-2020 Acura NSX, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for sealing the combustion chamber. It's designed with a 92mm bore and a compressed thickness of .036 inches, starting from a .027 inch shim layer, to ensure a tight seal between the cylinder head and the engine block. This is crucial for maintaining compression and preventing coolant or oil leaks, especially in higher-output engines.

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 environments and various surface finishes without needing additional sealants. This construction is well-suited for applications involving aluminum heads and blocks, or aluminum heads with cast iron blocks, as it can manage the stresses that arise from dissimilar metals.
