Reading the filename
The related catalog entry retains the base identifier 89663-05450. The (3) suffix in the filename is not described as a stock or modified variant label, so it should not be treated as evidence of a particular tuning feature or revision.
The exact vehicle application and compatibility cannot be established from this identifier alone. A matching calibration number is useful for cataloging, but it does not by itself confirm suitability for a particular control module or vehicle.
