Product Details
Cometic Gasket is known for making well-built gaskets that seal reliably, and this Multi-Layer Steel (MLS) head gasket is no exception. If you're working on the engine of your 1985-1995 Porsche 928, this gasket is designed to provide a strong seal between your cylinder head and engine block.
This MLS 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 conditions and surface finishes up to 482°F. The center layer is stainless steel, and its thickness can be varied to meet different requirements; in this case, it's set at .027 inches thick with a 100mm bore to match your 928's engine. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.
