Description

The Cometic C4167-040 is a premium multi-layer steel (MLS) cylinder head gasket engineered for select Honda D-series engines, including the D15Z1, D16Y5, D16Y7, D16Y8, and D16Z6. This gasket boasts a 78mm bore and a .040-inch thickness, ensuring precise fitment and optimal combustion chamber sealing for enhanced performance and durability. Constructed with a stainless steel outer layer that is coated with a high-temperature and chemical-resistant polymer, this gasket offers superior resilience. The addition of a PTFE (Teflon) topcoat further enhances its resistance to fretting and cold sealing issues. Cometic's MLS head gaskets are known for their ability to distribute pressure evenly across their entire surface, providing maximum tightness and longevity. Cometic is a globally recognized leader in gasket manufacturing, supplying championship-winning teams across various motorsports disciplines. This gasket is specifically designed for the following Honda engines: D15Z1, D16Y5, D16Y7, D16Y8, and D16Z6. The fitment is based on the product title and description, and buyers are encouraged to inquire if they require more information regarding specific vehicle compatibility, as the product may not be listed in all databases.
