OEM stands for Original Equipment Manufacturer and it means that the parts are made to the specifications set by the manufacturer specifically for your Ford vehicle. You can only purchase your Ford OEM parts from an authorized Ford dealer like Greenway Ford. OEM parts offer the quality and durability that comes with the Ford name. The parts are made specifically for your vehicle, so you know that will fit perfectly and work as if it just came off of the assembly line. OEM parts are very durable and come with a warranty from Ford, so you know you are buying a quality item that is backed by the manufacturer. You will not get this same guarantee with an aftermarket part for your Ford vehicle.
