These are originally manufactured parts for use in new vehicles. Car assembly lines often get new parts to assist in vehicle production. Manufacturers have to ensure that all the right parts are in position as they assemble parts. OEM parts are more expensive than other parts since they are original parts manufactured when the car is still new.

  • Replacement Parts

The manufacturer of a new car makes the replacement parts. Vehicle reliability and quality have increased, so it is only normal for parts to have high demand. Once a car is produced, a manufacturer can stock its parts for ten years.

  • Aftermarket parts

Aftermarket parts are those parts that aren't manufactured by the original car manufacturer. A car assembly line can have thousands of parts on it at a go. The small parts makeup subparts, and eventually, they all make up a fully functioning vehicle.
