Cometic Gasket
Cometic Gasket produces precision-machined engine sealing components used by professional engine builders and race teams worldwide. MLS head gaskets, intake gaskets, and complete engine gasket sets from Cometic are engineered to hold seal under the elevated cylinder pressure and heat cycling that OEM gaskets cannot always survive in high-performance applications.Popular UpgradesCometic MLS (multi-layer steel) head gaskets are the most-requested upgrade for turbocharged, supercharged, and naturally aspirated builds where cylinder pressure exceeds the limits of OEM composite gaskets. Available in bore sizes and thicknesses calibrated to manage compression ratio, Cometic MLS head gaskets are a standard specification for any serious engine build. Intake manifold gaskets, exhaust gaskets, and cam cover sets round out the range for complete engine assembly work.Why use Cometic MLS head gaskets over OEM?Cometic MLS head gaskets use multiple layers of embossed stainless steel that create a ...
