Cometic's MLS cylinder head gasket for BMW M20B25/M20B27 matches an 85mm bore at 0.068 in thickness to restore or upgrade engine sealing. The multi-layer stainless construction uses embossed outer layers coated in Viton for heat resistance to 250°C (482°F) and corrosion protection. The uncoated center shim can be varied for required thickness, while embossed faces help distribute load evenly and lower clamp load to reduce bore distortion.
