What’s the difference between OEM, aftermarket and OEM aftermarket parts?

Original Equipment Manufacturer parts are those which are fitted to your engine as standard at factory first fit.

Aftermarket parts are everything that is fitted to the engine after sale.

Aftermarket consists of a mixture of genuine OEM part as well as varying standards of copy components.
