The auto supplier's Cosma International unit is also spending $162 million for a die casting operation in Battle Creek, Mich., the Michigan Economic Development Corp. announced Jan. 23.

Final details have not been determined yet for the Magna Exteriors and Interiors operations, company officials said.
