Editing Original equipment manufacturer (section)

== Automotive parts ==
When referring to auto parts, OEM typically refers to the manufacturer of the original equipment, that is, the parts which are then subsequently assembled and installed during the construction of a new vehicle. In contrast, [[automotive aftermarket|aftermarket]] parts are those made by companies other than the OEM, which might be installed as replacements or enhancements after the car comes out of the factory. For example, if [[Ford Motor Company|Ford]] used [[Autolite]] [[spark plug]]s, [[Exide]] batteries, [[bosch (company)|Bosch]] [[fuel injection|fuel injector]]s, and Ford's own [[engine block]]s and [[cylinder head|heads]] when building a car, then car [[conservation and restoration of road vehicles|restorers]] and [[collecting|collectors]] consider those to be the OEM parts.<ref>{{Cite web|last=Khartit|first=Khadija|last2=Kvilhaug|first2=Suzanne|date=2015-04-15|title=What Is an Original Equipment Manufacturer (OEM)?

The OEM is the original producer of a vehicle’s components, and so OEM car parts are identical to the parts used in producing a vehicle. Aftermarket parts are produced by other vendors and do not necessarily have a consistent level of quality or compatibility with the vehicle.}}</ref><ref>{{Cite web|title=OEM - Encyclopedia|url=https://www.automotive-fleet.com/encyclopedia/oem|url-status=live|archive-url=https://web.archive.org/web/20200921135945/https://www.automotive-fleet.com/encyclopedia/oem|archive-date=2020-09-21|access-date=2024-06-19|website=Automotive Fleet|quote=In the automotive industry, OEM refers to the company that designs and manufactures the original components and systems used in vehicles during their initial assembly.}}</ref>  

Other-brand parts would be considered aftermarket, such as [[Champion (spark plug)|Champion]] spark plugs, [[DieHard (brand)|DieHard]] batteries, Kinsler fuel injectors, and BMP engine blocks and heads. Many auto parts manufacturers sell parts through multiple channels, for example to car makers for installation during new-vehicle construction, to car makers for resale as automaker{{nbh}}branded replacement parts, and through general merchandising supply chains. Any given brand of part can be OEM on some vehicle models and aftermarket on others.<ref>{{Cite web|last=Kagan|first=Julia|last2=Khartit|first2=Khadija|last3=Kvilhaug|first3=Suzanne|display-authors=1|date=2005-06-20|title=Original Equipment Manufacturer (OEM): Definition and Examples |url=https://www.investopedia.com/terms/o/oem.asp|url-status=live|archive-url=https://web.archive.org/web/20240104214032/https://www.investopedia.com/terms/o/oem.asp|archive-date=2024-01-04|access-date=2024-06-19|website=[[Investopedia]]|quote=In the auto repair industry, OEM parts are those products used by a car manufacturer.
