A new high temperature gasket is now used. The 4N-3955 Gasket is replaced by the 255-6863 Gasket (1). The 255-6863 Gasket provides a much higher temperature tolerance for the current engines. The new gasket is also a one crush gasket. The gasket needs to be aligned with the exhaust system before the four mounting clips are tightened to the turbocharger.
