Cometic Honda Civic 1.7L D171 79mm .027 inch MLS Head Gasket D17

Cometic Gasket is known for making well-built engine components, and this Multi-Layer Steel (MLS) head gasket is a prime example for your 2001-2005 Honda Civic with the 1.7L D17 engine. This gasket is designed to handle the demands of modern engines, providing a strong seal without needing any extra sealants. It's built to work well whether you have aluminum heads with an aluminum block or aluminum heads with a cast iron block, as the multiple steel layers can manage the stresses between different metals.

The strength of this MLS gasket comes from its multiple stainless steel layers, which also help it resist corrosion and maintain its shape. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This makes it suitable for tough sealing jobs and various surface finishes. The center layer is stainless steel and can be varied in thickness to meet different requirements; in this case, it's set to a compressed operating thickness of 0.027 inches with a 79mm bore, matching your Civic's specifications.
