Cometic Mitsubishi Lancer EVO 4-9 86mm Bore .030 inch MLS Head Gasket 4G63 Motor 96-UP

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example for your 2003-2005 Mitsubishi Lancer Evolution. If you're rebuilding the top end of your 4G63 motor, this gasket is designed to handle the pressures of high-output engines. It's made with multiple layers of stainless steel for increased strength and resistance to corrosion, which helps it rebound and maintain a seal even under stress.

The outer layers of this gasket are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating helps ensure a solid seal against both aluminum and cast iron blocks, and it doesn't require any additional sealants, making installation more straightforward. The center layer is stainless steel, and its thickness is varied to meet specific requirements, like the .030 inch compressed operating thickness on this particular gasket, which has an 86mm bore to match your engine.
