The Cometic MLS cylinder head gasket for Honda B18A1 and B18B1 engines is a .056in gasket with an 81mm bore designed for reliable sealing in high-output engines. It uses three to five layers of stainless steel with embossed outer layers coated in Viton and an uncoated stainless shim center. Suitable for aluminum-to-aluminum or aluminum-to-cast-iron combinations, the gasket needs no sealants, resists corrosion and rebounds under load for durable sealing.
