Auto parts significantly impact the capabilities and functions of your car. While there are many parts on the market, you can divide them into two categories: original equipment manufacturer (OEM) and aftermarket. If you’re not sure what these terms represent or which you should look for, below is a brief comparison.

What Are OEM Parts?

The same company that manufactures a specific car will design and produce these auto parts. As a result, they match the original parts inside a vehicle when you purchase it brand-new from a dealer.

When putting them into your vehicle, a mechanic won't have to do any fine-tuning, as they will fit into place and cooperate with the surrounding components. Therefore, they typically last longer, match your warranty, and provide superior performance. 

On the other hand, OEM auto parts can be more expensive than aftermarket components. However, many manufacturer warranties require mechanics to use these parts, which can protect your original investment.

What Are Aftermarket Parts?

These auto parts are not from the car’s original manufacturer, but instead, come from a third-party company that designs the pieces for specific vehicles. They vary widely in quality and function, and many of them are less expensive than OEM parts. If you can find aftermarket components that are direct replacements for your vehicle’s parts, you won’t have to worry about issues with performance or longevity. 

You’ll also have a greater variety of options to choose from, as there are many aftermarket part manufacturers. Some of them increase the performance of your vehicle, while others will only replace broken components. It’s also easier to find aftermarket parts, whereas you must typically order OEM parts from the manufacturer. If you decide to choose aftermarket parts, make sure that the installer will offer a warranty on their labor, as the car’s manufacturer likely won’t.
