Auto parts are the various components of an auto which collectively make up the car. Car parts can consist of windows, hub caps, wheels, engines, tires, wheels, and interior details. The parts which make up a car are all manufactured and distributed in a variety of ways. OES and OEM auto parts are also known as factory parts and are those which are distributed by the original car manufacturer, just like the parts which come with the original vehicle. These parts may require special ordering and expediting and may bear a markup in price as the result of their brand name.http://www.autohausaz.com/html/auto_parts_shopping.html

Aftermarket parts basically imitate those that the auto manufacturers brings to market, offered at a lower or discounted price. Aftermarket part producers purchase rights and plans to auto manufacturers' part designs and may produces a product which is enhanced from the original factory version available at a lower price due to large scale distribution to nationwide wholesalers.http://www.thepartsbin.com/oem_vs_aftermarket.html
