Cometic's MLS cylinder head gasket for BMW M42B18/M44B19 fits 85mm bores with a 0.036 in gasket thickness to restore dependable sealing on high-output builds. The multi-layer stainless construction uses embossed outer layers coated with Viton for heat resistance to 250°C (482°F) and corrosion protection. A central uncoated stainless shim permits thickness variation while the embossed faces conform to surface finish and lower clamp load to limit bore distortion.
