Cometic Porsche 928 83-97 104mm Bore .045 inch MLS Head Gasket Left Side H/G

This is the left side Multi-Layer Steel (MLS) head gasket for your Porsche 928, designed for engines with a 104mm bore and a compressed thickness of .045 inches. MLS gaskets are built with multiple layers of stainless steel, giving them increased strength and the ability to rebound, which helps them seal effectively even with different block and head materials like aluminum to cast iron. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and surface finishes without needing additional sealants.

Cometic constructs these gaskets with embossed outer layers that are coated on both sides with Viton, a material rated for temperatures up to 482 degrees Fahrenheit. The center layer is stainless steel and can be varied to achieve different thickness requirements, like the .045 inch compressed thickness found in this specific gasket. This construction makes them a solid choice for high-output engines, offering reliable sealing performance.
