The Cometic MLS head gasket for BMW S14B20/S14B23 engines (94.5mm bore, .027" compressed thickness) is a multi‑layer steel design that delivers high sealing performance without additional sealants. Embossed outer layers are coated with Viton for heat and chemical resistance up to 250°C, while an uncoated stainless shim center allows thickness variation. MLS construction improves rebound, corrosion resistance and load distribution.
