Part number 930-123-194-03 is an earlier revision of the Genuine Porsche Turbocharger Wastegate Gasket (exhaust flange gasket) for the Porsche 911 Turbo (930), 964 Turbo, and 924 Turbo. Alternate numbers = 930-123-194-06 and 930-123-194-07. This and other Porsche items on the site were spares purchased for my 1987 911 turbo.
Slight blemish on one side of the gasket-will not affect the gasket's function.
