Reading the catalog filenames
GS300 3GRFSE 89663-30k80-A.EPR and GS300 3GRFSE 89663-30k80-A.MPC name the same vehicle, engine and calibration identifier with different file extensions. The separate listing 89663-30K80-A carries the same calibration identifier without a filename extension.
The -A suffix is part of the listed identifier. None of these names describes a modified feature or identifies a performance variant. The GS 300 and 3GR-FSE labels provide useful context for distinguishing this record, but they do not establish compatibility with every vehicle carrying that engine.
