Cometic's MLS cylinder head gasket for BMW M42B18/M44B19 is sized for an 86mm bore with 0.098 in thickness to provide durable sealing for engine rebuilds. The multi-layer stainless design includes embossed outer layers coated in Viton for heat resistance to 250°C (482°F) and corrosion protection. An uncoated center shim accommodates different thicknesses while embossed faces conform to finish, equalize load distribution and reduce clamp load to limit bore distortion.
