Cometic Porsche 997.2/991.1/991.2 A170/MA1.71/MA1.75/MA1.76/Etc. .052 105mm Bore MLX LHS Head Gasket

If you're rebuilding the top end of your 2009-2018 Porsche 911, getting the right head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and engine block without needing any extra sealants.

Cometic constructs these MLS gaskets using multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different surface finishes. The center layer is stainless steel, and its thickness can be varied to meet different requirements; this particular gasket has a compressed thickness of .036 inches and a bore size of 105mm, designed for the left-hand side (LHS) of your engine.

This gasket is designed to work effectively with both aluminum heads and blocks, or a combination of aluminum heads and cast iron blocks, and can withstand the forces created when these different materials meet. It's a well-built component that helps ensure your engine's combustion chambers are properly sealed.
