About this part

Product Details

If you're rebuilding the top end of your 2001-2005 Honda Civic with the 1.7L D17 engine, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of modern engines.

Cometic's MLS design 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 different surface finishes, making it suitable for aluminum heads to either aluminum or cast iron blocks. With a compressed operating thickness of 0.027 inches and a 77mm bore, this gasket is designed to fit your D17 engine precisely and requires no additional sealants.
