The Cometic MLS cylinder head gasket for Honda B18A1 and B18B1 engines is a .140in gasket with an 81mm bore intended for heavy-duty sealing scenarios. Built from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless shim layer, it requires no sealants and accommodates aluminum-to-aluminum or aluminum-to-cast-iron pairings. The multilayer construction rebounds under load, resists corrosion and helps manage clamp load distribution.
