Cometic Mitsubishi Eclipse/Galant/Lancer (thru Evo 3) 4G63/T 86mm .056 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with embossed outer layers coated in Viton, a heat-resistant rubber material rated up to 482°F. It's designed specifically for the 4G63 and 4G63T engines found in many Mitsubishi Eclipse, Galant, and Lancer models, including the early Evo 1-3 variants, with an 86mm bore. The compressed operating thickness is .056 inches, providing a solid seal for high-output engines.

MLS gaskets are well-suited for joining aluminum heads to either aluminum or cast iron blocks because their multiple stainless steel layers can handle the shearing forces that can occur between these different metals. This construction also increases the gasket's strength and resistance to corrosion, while the stainless steel allows it to rebound effectively. The Viton coating on the outer layers is tough enough for demanding sealing environments and various surface finishes, meaning you don't need to add extra sealants during installation.
