Cometic's MLS cylinder head gasket for BMW M20B25/M20B27 is sized for an 85mm bore with 0.045 in thickness to provide dependable sealing on refreshed engines. Its multiple stainless steel layers include embossed outer faces coated in Viton for heat resistance to 250°C (482°F). The center uncoated shim allows thickness variation while the embossed layers conform to finish, distribute clamping load and reduce the clamp load needed to limit bore distortion.
