Supertech Mitsubishi 4G63 EVO 4-8 86.3mm Bore .051in (1.3mm) Thick MLS Head Gasket

This is a Supertech multi-layer steel (MLS) head gasket specifically for the Mitsubishi 4G63 engine found in EVO 4-8 models. It features an 86.3mm bore and is 1.3mm thick, designed to seal the combustion chamber and coolant passages between the cylinder head and engine block.

MLS head gaskets are well-built for high-performance applications because they offer excellent sealing under demanding conditions. The multiple layers of stainless steel, combined with a specialized coating, allow this gasket to conform to surface irregularities while resisting blowout from high cylinder pressures. This particular gasket is a direct replacement for stock, making installation straightforward if you're rebuilding your top end or replacing a blown head gasket.
