About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on the K20Z3 engine in your 2006-2011 Honda Civic SI, this gasket is built to handle the demands of high output. It's designed to provide maximum sealing performance without needing any extra sealants, making the job straightforward.

This gasket 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 tough sealing environments and various surface finishes. The compressed thickness is 0.027 inches, and the 86mm bore is specific to your K20Z3 engine. These MLS gaskets work well whether you have aluminum heads with an aluminum block or aluminum heads with a cast iron block, as they can manage the shearing forces between different metals.
