Cometic MLX cylinder head gasket for the Mitsubishi 4G63T (Evo 9 only) is a .052" multi-layer gasket with an 87mm bore that uses an integrated "stopper" layer for combustion chamber sealing. The MLX design improves clamp load around the cylinder without increasing bore distortion, making it suitable where precise sealing and cylinder clamp are required for the specified Evo 9 application.
