Reference projects of the Automotive business unit.

Our fans, shrouds, module carriers and net wind deflectors set standards around the world. This is one of the many reasons why leading manufacturers as well as tier 1 and 2 suppliers rely on the Wirthwein brand quality. We ask you for your understanding that we have to keep some projects back from you due to nondisclosure agreements.
