Cometic's MLS cylinder head gasket for BMW M42B18/M44B19 fits an 86mm bore at 0.027 in thickness, intended to provide reliable sealing for engine rebuilds and performance applications. The multi-layer stainless construction features embossed outer layers coated with Viton to resist heat to 250°C (482°F) and corrosion. A central uncoated shim allows thickness variation while the embossed faces improve load distribution and reduce required clamp load.
