The Cometic C5780-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Porsche 928 models equipped with M28 series engines. This precision gasket features a .040" (1.02mm) compressed thickness and is designed to accommodate a 100mm cylinder bore.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• .040 inch compressed thickness provides enhanced sealing under high compression
• 100mm bore diameter designed for Porsche M28 engine specifications
• Compatible with M28.41, M28.42, M28.43, M28.44, M28.45, M28.46, M28.47, M28.49, and M28.50 engine variants
• Right-hand side (RHS) application for proper cylinder bank installation
• Embossed stainless steel layers with Viton rubber coating resist heat and pressure

Cometic's MLS head gaskets utilize multiple layers of stainless steel with advanced coating technology to create a superior seal between the cylinder head and engine block. The gasket's ability to recover from thermal expansion cycles makes it ideal for both street and performance applications. This design eliminates the need for retorquing and provides consistent clamping pressure across the entire sealing surface.

Note: This gasket is sold individually and covers one cylinder bank. Porsche 928 V8 engines require two head gaskets (left and right) for complete installation.
