OEM stands for Original Equipment Manufacturer. These are the same parts that are purchased from suppliers by car manufactures to install on cars that are coming off the assembly line as well as for repair of cars in the dealership. Most often, the only difference is the packaging that the parts are delivered in. Sometimes, the manufacturer must remove any car brand logos that are etched into the part but that has no effect on the performance or warranty of the part. Rest assured that this part is the exact part that you would get in a Genuine package.
