When you go to the dealer for a car repair, you’ll almost always get parts from the original equipment manufacturer (OEM). On the other hand, visiting an independent car repair shop will give you a choice between OEM and aftermarket parts.
Picking between these parts requires careful consideration of the benefits and drawbacks of each option.
OEM Parts
The same manufacturer who made the original part also makes the original equipment manufacturer (OEM) vehicle parts. Many car and truck companies offer several tiers of the parts, including the highest quality ones that only they make.
These parts carry a warranty, usually for twelve months or 12,000 to 50,000 miles, and vehicle owners can purchase them directly from the manufacturer or a car dealer. OEM parts are designed to fit the vehicle, and the car’s computer system recognizes them automatically.
Aftermarket Parts
Aftermarket car body parts serve to fit a number of vehicles and are not made by the same car manufacturer. For example, a different manufacturer or a company that reverse-engineered a part that the car uses can make these parts.
These are usually less expensive than OEM parts, and some aftermarket parts are quite similar to OEM parts in appearance, fit, and function. However, you need to be careful about scrutinizing the quality of aftermarket parts as it varies widely.
A study commissioned by the Department of Transportation found that nearly half of all recalls were for aftermarket parts in some cases. In other words, aftermarket parts are not always a good choice for your car.
Some examples of aftermarket parts include:
- Brake shoes
- Sensors
- Alternators
- Belts and hoses
- Headlight bulbs
- Air filters
- Valvetrain components
- Drive axles
- Fuel pumps
What Makes Aftermarket Parts Different?
Several factors make aftermarket parts different from OEM parts. Aftermarket parts are not always designed to fit the vehicle. Auto manufacturers often use parts designed to fit a wide range of cars, which results in problems if the aftermarket part doesn’t fit your specific vehicle.
In addition, aftermarket part manufacturers don’t have to go through the rigorous testing that OEM parts must pass to be certified as safe and legal for use.
For these reasons, aftermarket parts are not always as safe as OEM parts, and they are not always made of high-quality materials. Sometimes, aftermarket parts don’t last as long as the original parts.
How to Choose between OEM and Aftermarket Parts
If you are faced with choosing between an aftermarket and OEM part, you must weigh the quality and cost of the parts and decide whether it is worth the gamble to select an aftermarket option. You can do this by considering a few things:
-
Look into the Warranty
OEM parts usually come with a warranty. As long as it is within the warranty period, you can get the part replaced if it is defective.
For example, if your alternator breaks, you can get a new one from the manufacturer under warranty. On the other hand, aftermarket parts usually do not carry a warranty. If you receive a part that doesn’t work, you have no recourse for a refund or replacement.
-
Consider the Difference in Quality
OEM parts usually have higher quality than aftermarket parts. In some cases, aftermarket parts are as high quality as OEM parts. In general, however, it makes sense to choose OEM parts unless you have a specific reason to go with aftermarket ones.
How to Know if Parts Are OEM or Aftermarket
Unfortunately, there are no reliable ways to distinguish between OEM and aftermarket parts. In some cases, the parts are labeled as either OEM or aftermarket. For example, aftermarket fuel pumps are often marked on the box. However, in other circumstances, there is no way to tell what you are getting.
Conclusion
In most situations, it is best to go with OEM parts. This can help you ensure that the part will fit your vehicle and last for a long time. On the other hand, you can also opt for aftermarket car parts because of their benefits. In this case, make sure you choose a supplier with reliable service and an outstanding reputation.
