Cometic's MLS head gasket for BMW M54B25/M54B30 engines is an 85mm bore, .051" compressed-thickness multi-layer steel gasket with embossed outer layers coated in Viton. Designed for aluminum-to-aluminum or aluminum-to-cast-iron applications, the construction rebounds to resist corrosion and seal under varied loads without sealants, improving load distribution and reducing bore distortion.
