The HKS GT28R extension gasket is a flange gasket specified to extend or adapt exhaust connections for GT28R turbo applications. It serves as a replacement sealing component where an extension or modified joint is required, helping prevent leaks at the flange and supporting proper exhaust routing on GT28R-equipped installations.
