Cometic Porsche 997 3.6L Twin Turbo 106.5mm Bore .030 inch MLS Head Gasket

When you're rebuilding the top end of your 2005-2012 Porsche 911's 3.6L twin-turbo engine, getting the cylinder head gasket right is critical for proper sealing and performance. This Multi-Layer Steel (MLS) gasket from Cometic is specifically made for that job, ensuring a solid seal between your cylinder head and engine block.

Cometic builds these gaskets using multiple layers of steel, which gives them the strength to handle the high pressures and temperatures found in performance engines like the 997's. The outer layers are coated with Viton, a material known for its resistance to oil and heat, helping to maintain a tight seal over time. This particular gasket is designed with a 106.5mm bore and is .030 inch oversize, which is important to note if you're machining your block or heads to specific tolerances.

Using an MLS gasket like this one is a common practice for many performance builds because of its durability and ability to conform to slight imperfections on the mating surfaces, helping to prevent leaks and maintain compression.
