Aftermarket parts vs OEM parts


Aftermarket parts vs OEM parts

If you take your car to a dealership for service, you will get OEM (Original Equipment Manufacturer) parts. If you go to an independent shop, you will most likely (though not necessarily) get aftermarket parts. Many people assume that OEM is better, and worry that aftermarket parts may not be up to par. Is there any truth to this belief? Or does it make sense to save money by using aftermarket parts? What’s the difference, anyway? If you are looking to upgrade your current vehicle and add parts that increase the horsepower or performance, it stands to reason that you will want to add parts that won’t harm your vehicle. Additionally, you will want to make sure you are adding parts that are recommended by your technicians who are doing the work. In this blog by Pfaff Tuning, we share some information about aftermarket parts vs OEM parts for your vehicle. 

OEM Parts 

As the name suggests, OEM parts are made by the manufacturer. They are exactly the same as the parts that your vehicle was built with. There are many advantages that come with using OEM parts.

No comparison shopping:

If you request a particular part at a dealership, you will receive the one that matches your vehicle. You don’t need to worry about comparison-shopping.

Quality assurance and warranty:

You can be 100% certain that the OEM part works identically to the one it’s replacing. You will normally receive a one-year parts and labor warranty as well.

Familiarity with technicians:

If you need to have a part replaced on your vehicle due to an accident or malfunction, then OEM parts are highly recommended. This is due to the fact that your technicians will be familiar with these parts and how they work, especially with your vehicle type. 

Aftermarket Parts 

An aftermarket part is any part that is made by someone other than the vehicle manufacturer. Contrary to a popular myth, using aftermarket parts does not void the car’s warranty as long as they are direct replacements. Many aftermarket parts function just as well as, or even better than, the OEM version. Still, like OEM parts, aftermarket parts also have their own advantages.


Aftermarket parts are made by reverse-engineering the OEM part, which can sometimes mean fixing some original weaknesses. You can also decide what’s most important to you. For example, you might find an aftermarket brake pad that stops the car even more efficiently than the OEM pad, but at the cost of a little extra noise. You get to decide whether the improved stopping distance is worth the noise.


Aftermarket parts are readily available at your choice of independent shop. As long as you trust your auto tech to make good choices regarding quality, you can get the work done quickly wherever you like.


You can get aftermarket parts that help you achieve the look of performance you are going for in your vehicle. Whether it is improving the horsepower, the handling, or the aesthetic appeal, you can find the aftermarket parts you are looking for.
