About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.040 inches and a 102mm bore, specifically designed for the 2001-2005 Porsche 911. MLS gaskets are a strong choice for high-output engines because they are made from multiple layers of stainless steel, which helps them rebound and resist corrosion. This construction also allows them to handle the shearing forces that can occur between aluminum heads and aluminum or cast iron blocks.

The outer layers of this gasket are coated on both sides with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. Viton is chosen for its ability to perform in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements. Because of their robust construction, these MLS gaskets do not require any additional sealants for installation.
