GrimmSpeed EJ25 Head Gasket Set 1.5mm


Description:The GrimmSpeed Head Gaskets feature a multi-layer steel (MLS) construction, in which multiple grades are used to provide optimal surface and combustion chamber sealing as they are torqued down. The top and bottom layers feature a Nitrile Rubberized Coating that helps accommodate a rougher RA surface finish of up to 50microinch. This acts to better seal the non-critical areas of the gasket. In addition, the gasket edge includes a folded stopper layer that allows for optimal sealing for the combustion chamber. This is done to help reduce the chances of combustion gasses causing head gasket failures under extremely high cylinder pressures that built engines can experience.
