Our purpose is to support owners in their use and maintenance of the Porsche 928 and to foster camaraderie among owners throughout the world.

The Option Codes below are prefixed by 'M' for ease in data handling, but Porsche used both 'M' and 'I' as prefixes (likely never for the same Option). To search for an option, use the 'M' prefix, even if the code you're looking for is an 'I' code.
