Cometic’s MLX cylinder head gasket for 2020+ BMW S58B30T0 engines (.055" thickness, 85mm bore) features an integrated "stopper" layer to enhance combustion chamber sealing. The MLX construction improves clamp load distribution around the cylinder without increasing bore distortion, providing a sealing upgrade where additional clamp loads are beneficial for engine reliability under higher stresses.
