Cometic's .084 in MLS cylinder head gasket for BMW M20B25/M20B27 is sized for an 85mm bore to provide reliable sealing on rebuilt or high-output engines. The gasket stacks multiple stainless steel layers with embossed outer faces coated in Viton for heat resistance to 250°C (482°F). A central uncoated shim allows thickness variation while embossed layers conform to surfaces, distribute load evenly and reduce clamp load to limit bore distortion.
