The invention discloses an automotive PET profile air duct and a manufacturing method thereof, and belongs to the technical field of automotive interiors, and the air duct comprises a PP air outlet, a PET pipe body and an HDPE connector; an air inlet port of the pipe body is connected with the connector, and an air outlet port of the pipe body is connected with the air outlet. According to the invention, the PET profile with the thickness of 10-14mm and the density of 400 +/-10g/cm < 2 > is produced through the development of hot press molding and a welding process, and the PET material is used for replacing a PP material used in a traditional air duct, so that the assembly applicability, the aging resistance and the combustion resistance of the whole air duct are effectively improved, and compared with the existing air duct with the same specification, the air duct has the advantages that the production cost is reduced, and the production efficiency is improved. The overall service life of the air pipe is prolonged by more than three years, and the safety and economical efficiency of the air pipe in automobile application are improved.
