Cometic Porsche A101/A103/A170/MA1.24/MA1.71/MA1.75 .052in MLX Cyl Head Gskt-105mm Bore-Cyls 4-6-RHS

This Cometic Multi-Layer Steel (MLS) head gasket starts with a .052 inch thickness and a 105mm bore, designed for specific cylinders on a range of Porsche and Jaguar engines. The multi-layer stainless steel construction offers increased strength and the ability to rebound, helping it withstand the forces between aluminum heads and blocks, or aluminum heads and cast iron blocks. This makes it a solid choice for high output engines where a reliable seal is critical.

The outer layers of this gasket are embossed and coated on both sides with Viton, a heat-resistant rubber material rated up to 482°F (250°C). Viton is known for its ability to handle harsh sealing environments, varying load conditions, and different surface finishes. The center layer is uncoated stainless steel, allowing for variations in thickness to meet specific engine requirements. Because it's an MLS gasket, it seals effectively without needing additional sealants.

This gasket is suitable for a variety of Porsche models like the 911 (2009-2018), Boxster (2016), and Cayman (2016), as well as Jaguar XK models from the 1940s through the early 1960s. It's built to provide maximum sealing performance for demanding applications.
