Cometic Mitsubishi 4G63/T (Eclipse/Galant/Lancer Thru EVO3) 87mm .070 inch MLS Head Gasket

This product is a Cometic Multi-Layer Steel (MLS) head gasket designed for specific Mitsubishi 4G63 and 4G63T engines, including those found in the 1990-1992 and 1995-1999 Mitsubishi Eclipse, as well as certain Galant and Lancer models up through EVO3. It features an 87mm bore and a compressed thickness of .070 inches, making it suitable for rebuilding or replacing the head gasket on these popular performance engines.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even under demanding conditions. This construction means the gasket doesn't require additional sealants and is effective with both aluminum and cast iron engine blocks, handling the stresses that can arise from dissimilar metals.

The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, with this specific gasket set to .070 inches when compressed. This updated design helps provide maximum sealing performance for engines that produce higher output than stock.
