The Cometic MLS cylinder head gasket for Renault F4P/F4R (83mm bore) features multi-layer stainless steel construction with a compressed operating thickness of 0.040in. It seals high-output engines without sealants and suits aluminum heads paired with aluminum or cast-iron blocks. Embossed outer layers are coated with Viton and AMP for heat and chemical resistance while an uncoated center shim allows thickness variation. The layered design rebounds, resists corrosion, lowers clamp-load needs, reduces bore distortion and evens load distribution across the sealing area.
