What is the difference between oem and aftermarket auto parts – car talk – nigeria gas utility


OEM parts are Original Equipment Manufacturer parts.This means it is a vehicle part made by the car manufacturer. Many automotive companies also use outside manufacturers to design and produce the parts used on the vehicle and then the dealer adds their logo and packages it in their custom packaging.

Aftermarket parts on the other hand are produced by a different company than the car maker. While these parts are usually made with the same materials and made to serve the same purpose,they may have slight differences in how they look and feel.Some aftermarket parts,due to redesign, may actually be an improvement on the original.

When you take your car to the dealership’s service department, say Elizade, for repairs, you know you’re getting Original Equipment Manufacturer (OEM) car parts. However, if you take your car to an independent mechanic, you’ll most likely get aftermarket car parts. Is there anything wrong with that? Does a less expensive part mean a poorer-quality part? And in what situations should you use only OEM parts?

Quality can be equal to or greater than OEM: In some cases, you may end up with a better part than you started with. The aftermarket companies reverse-engineer the part, and work the weaknesses out. For example, when an automaker designs its brake pads, it has to strike a balance between cost, durability, noise levels and performance. If you want better performance and don’t mind some extra brake noise (some brake pads squeak even though they are stopping the car effectively), an aftermarket pad may be your best choice.

More variety: There are hundreds of companies that make aftermarket parts. Some specialize in specific parts, and other companies make almost any part you can think of. More variety means greater selection and a wider range of prices. You can walk into any auto parts store or local mechanic, and they’re bound to have a part that fits your car. This gives you more options on where to take your car for service.

Quality varies greatly: The saying "you get what you pay for" rings true here. Some aftermarket parts are inferior because of the use of lower-quality materials. Stick with aftermarket brands you’re familiar with or are recommended by a mechanic you trust, even if these parts cost a bit more.

Overwhelming selection: If you’re not familiar with aftermarket brands, the selection could be overwhelming, and there’s some chance you may get a bad quality part. Even a part as simple as a spark plug can be made by dozens of different companies and comes in numerous variations.

Quality may not be superior: You paid the extra money for an OEM part, hoping that it was vastly better than an aftermarket part. But that may not always be the case.Some aftermarket parts are equal to or in some cases better than OEM parts. So you might be paying extra just for the name.

All aftermarket parts are not created equal — but all OEM parts are. This creates its own set of advantages and disadvantages. If you’re familiar with a number of brands or work on your own car, aftermarket parts can save you a lot of money. If you’re not familiar with aftermarket brands, prefer to have everything done at the dealership and don’t mind paying a bit extra for that peace of mind, OEM is a good choice for you.

Car parts is a numbers game, by law if you make any component in the US you have to make the spec available for others to make so people who need it in other parts of the world don’t have to come to you, that is how patent and licensing works.

Companies like Bosch and Delphi( http://delphi.com/) might develop a better electrical system than the one currently on cars so they start selling it on the market and the automakers adopt it, or the manufacture outsource parts to vendors(the make parts to carmaker spec with carmaker logo on it)e.g Jaguar, for engines, Bently, BMW engines, Lots of carmakers use Aisin transmissions.Its better/cheaper to make one component that fits into a dozen models than a dozen models that use specific parts and even cheaper when its made by someone else to fit multiple manufacturers and this is where we use service parts.

When it comes to service parts like brakes, filters, lubricants, tires, suspension components, and sensors. Cars are made to use components available in the market.GM,Ford,and Toyota are not in the brake business so they use parts made by Wagner, Brembo, Federated etc. same for shocks, lights, tires, exhaust, bearings etc.

There are specialized part of the car that need a different type of vendors and sometimes collaboration between auto makers, like the differential, transfer case, entertainment system for these you need companies like Dana, Bose,karma kardon, new venture gear( http://en.wikipedia.org/wiki/New_Venture_Gear)
