Cometic MLS head gasket for BMW S14B20/S14B23 engines, 93.4mm bore and .051" compressed thickness. Constructed from multiple embossed stainless steel layers with Viton-coated outer faces to resist heat and corrosion, the gasket rebounds under load and does not require sealants. The uncoated shim layer allows thickness variation while improving sealing across differing head/block material combinations and reducing bore distortion.
