Cometic 06-09 Honda Civic Si K20Z3 2.0L 86mm Bore .098in MLS Head Gasket

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a solid choice for your 2006-2011 Honda Civic Si. This gasket is designed to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and engine block without needing any extra sealants. It's built to work with both aluminum and cast iron blocks, and its construction helps resist the shearing forces that can occur when different metals are joined.

The strength of this gasket comes from its multiple stainless steel layers, which also give it the ability to rebound and resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is stainless steel and can be varied in thickness, which is how Cometic achieves the specific 0.098-inch compressed operating thickness for this gasket. This design helps ensure a consistent and strong seal, even under demanding conditions.
