The sealing performance has been improved considerably with the super grommet,to suit these engines and has been proven to brliver excellent relibility.
SUPER GROMMET TYPEThe dual sealing method of the bead structure & metal grommet, provides maximum sealing for the coolant, oil & gases around the bore circumference.
■ Heat Conductivity & The Strength of Stainless Steel
Stainless steel was chosen to be the material of choice to make the Metal Gaskets with because of the heat conductivity efficiency of the stainless steel material to evenly distribute the heat and aid with cooling. This will greatly improve reliability and reduce the chances of problems. The natural high tensile qualities of Stainless Steel greatly helps with increasing the joint ridged of the cylinder head with the cylinder block. This helps minimize the engine from warping when under severe stress loads that performance engines go through when running high power applications. The result is improved durability and added power gains.
■ ABOUT MARKING
All our metal head gaskets are laser marked with Models, Bores, Thickness, and TOMEI POWERED INC. company name. Since there are similar/counterfeit goods on market, please make sure logos on Gasket.
