Automotive repairs and car maintenance sometimes require replacing car parts. If you bring your vehicle to a dealership service center or mechanic, the service technicians will use either OEM parts or aftermarket parts to fix your vehicle. These parts are similar but there are some important differences to know about before you have your vehicle. Find out if one is better than the other when it comes to aftermarket vs OEM.
Original equipment manufacturer parts, or OEM parts, are made by your vehicle’s manufacturer for your specific make and model. OEM parts are used at dealership service centers, including the Whitten Brothers Automotive Service Center. Certified technicians are trained on each brand and the specific car parts and accessories.
Aftermarket parts, sometimes also known as alternative parts, are made by third parties and designed to fit various vehicle makes and models. Independent mechanic shops typically use aftermarket parts for services and repairs. You can also purchase them from in-person and online automotive stores.

There are pros and cons to both OEM parts and aftermarket parts. See how they compare in terms of price, availability, and more.
OEM parts generally come with a higher price tag than aftermarket parts, but you know you’re getting parts and car accessories made for your specific vehicle.
Because aftermarket parts are made to fit a range of vehicles, there is a wider selection to choose from. They’re also more readily available, and you can purchase them yourself. OEM parts have less of a selection and can typically only be purchased through the dealership. Having to research the best aftermarket parts for your needs can be overwhelming. With OEM parts, you know they’ll work because they’re made for each individual make and model.
You can trust that OEM parts and accessories are high-quality because they’re made directly by the automotive manufacturer and designed to fit perfectly in or on your vehicle. The quality of aftermarket parts can vary. While some are high-quality, you’ll have to do your own research on this as well.
Because OEM parts are made to fit your vehicle, they have better reliability, and you’ll know that your vehicle will continue to run as it should. They’ll also often be longer-lasting than aftermarket parts. Aftermarket parts can be reliable, but the reliability can vary from part to part. You won’t know what the longevity of the part is, and it may not last as long as an OEM part.
Most OEM parts are covered by a warranty. The manufacturer will cover the cost if the part doesn’t work correctly or is defective. Manufacturers also sometimes offer incentives or discounts on OEM parts when you bring your vehicle to a dealership service center. At Whitten Brothers Automotive, we have discounts on car parts and accessories. In contrast, aftermarket parts are not typically covered by a warranty, so if the part doesn’t work, you’ll have to pay to replace it.

While aftermarket parts may be more affordable upfront, they may not be as reliable or as high quality as OEM parts. This can cost you more in the long run if they have to be replaced sooner or if the parts don’t work in your car and you have to exchange them.
OEM parts can give you peace of mind that you’re getting the highest quality car parts made especially for your vehicle, and if you have an issue within the warranty timeframe, the part should be covered.
