Cometic's MLS head gasket for BMW S14B20/S14B23 engines is a 94.5mm bore, 0.070" compressed-thickness multi-layer steel gasket with embossed outer layers coated in Viton. Built to seal high-output engines without sealants, it handles aluminum-to-aluminum or aluminum-to-iron joints, reduces required clamp load, helps distribute sealing load evenly, and resists corrosion through its layered stainless construction.
