OEM is an acronym for Original Equipment Manufacturer. This means the manufacturer of the components in a product was produced by another manufacturer, for use in another product. In the auto parts industry, it would be the manufacturer of the original part installed in a vehicle at the time of production.
OEM replacement parts are recommended for most auto body repairs, and many mechanical repairs as well. There are many reasons why mechanics recommend using OEM replacement parts for car repairs, and you can find out more Benefits of OEM Parts on the NEATR blog.
