It is impossible for any automaker to manufacture all the parts that go into their vehicles. They often contract well-known automotive suppliers to design and produce the parts for them. These companies are known as OE Suppliers, and they are the ones who originally manufactured and supplied the part to be assembled along with the rest of the vehicle. It is perfectly acceptable to use reproduction parts, but original equipment parts are the best at bringing your vehicle back to perfect form and functionality. The most famous and ubiquitous OE suppliers include companies like VDO/Seimens, Gates, and TRW.
