Cometic MLX head gasket for Subaru EJ25 applications (2004–2006 EJ257, 101mm bore, .040") uses an integrated stopper layer for improved combustion chamber sealing. MLX technology enhances clamp load around the cylinder without increasing bore distortion, and the embossed outer layers are coated with Viton to improve sealing performance in demanding engine conditions.
