Cometic 01-04 Porsche 996TT 3.6L 102mm Bore .036in MLS Head Gasket

If you're rebuilding the top end of your 2001-2005 Porsche 911, a solid head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines like the M96.70 series found in your 996 Turbo.

Cometic 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 temperatures up to 482°F (250°C) and works well with different head and block materials, including aluminum and cast iron. This construction means the gasket seals effectively without needing any additional sealants, and the center shim layer can be varied to achieve different thicknesses, with this specific gasket set to a compressed operating thickness of 0.036 inches and a 102mm bore.
