Cometic's MLS cylinder head gasket for BMW M20B25/M20B27 fits an 85mm bore with 0.066 in thickness to support reliable sealing for rebuilt or modified engines. Constructed from several stainless steel layers, the embossed outer faces are coated with Viton to resist heat to 250°C (482°F) and corrosion. A central uncoated shim permits thickness changes while the embossed layers improve load distribution and reduce clamp load to minimize bore distortion.
