If you are ever on the market for new parts for your vehicle, you may see OEM and OES abbreviations at some point.

When buyers are looking for the most reliable part or value-friendly part, these abbreviations are not particularly friendly to ordinary consumers, which can be frustrating, especially when the definitions are so similar.

Nevertheless, if you are looking for auto parts, it is helpful to understand the meaning behind the codes and terms. What is the difference between OEM, OEM and aftermarket parts in the auto parts industry?

First, OES stands for original equipment supplier, while OEM stands for original equipment manufacturer. Many of the sections you will encounter fit into one of these categories.

People are sometimes confused because the definitions themselves are very similar. Simply put, an original equipment supplier part is manufactured by the manufacturer of the original factory part that made your car model. On the other hand, the original equipment manufacturer may not have manufactured the specific parts for your car, but has a formal contract history with the car manufacturer.
