This Cometic MLS cylinder head gasket is for Porsche 47-series and M31 engine variants, specified with an 88mm bore and about 0.036" thickness. It uses embossed stainless outer layers coated with Viton and an uncoated stainless shim for thickness control. The MLS design seals mixed head/block pairings without sealants, resists shear between materials, and offers corrosion-resistant rebound under demanding conditions.
