Wiseco Head Gasket - Nissan RB25 2.5L 87mm Gasket

Wiseco sport compact MLS head gaskets use a high-pressure steel-laminate design to withstand extremely high sheer forces that occur between an aluminum head and iron block. Internal embossments expand with heat to create a better seal when under extremely high combustion pressures and temperatures, conditions that are present especially in power-adder applications.
