Cometic's .066 in MLS cylinder head gasket for BMW M54B25/M54B30 fits an 85mm bore and delivers high sealing performance without sealants on modern engines. Multiple embossed stainless layers with Viton-coated outer faces resist heat to 250°C (482°F) and corrosion. The uncoated center shim permits thickness adjustment while the MLS design evens load distribution, reduces clamp load and handles aluminum-to-aluminum and aluminum-to-cast-iron mating surfaces.
