OEM (Original Equipment Manufactured) – When referring to automotive parts, OEM designates a replacement part made by the manufacturer of the original part. As most cars are originally assembled with parts made by companies other than the one whose badge appears on the vehicle, it may happen that a car company sells OEM spare parts without claiming to have manufactured the part itself.
Aftermarket – Copied from the original factory part and manufactured by a 3rd party supplier. Mainly manufactured overseas and imported into the US. They are certified and tested, and backed by a warranty offered by the company.
Recycled Part/LKQ Parts/Used Parts: Recycled parts and Like Kind and quality parts are original factory parts that have been removed from another vehicle of the same make and model, or a substitutable make and model, and have then been returned to “as new” condition.
