Comparing OEM vs. Aftermarket vs. Used Auto Parts

The car parts industry is on the rise. Evidence suggests that the automotive products market is expected to grow by 1.20% until 2029. But one car part hijacked the spotlight last year. Did you know that lightweight bumpers made of plastic were the most sought-after car parts in the U.S. online?

No matter what car parts you’re planning to replace, learn the replacement options offered first. If you’re currently struggling to understand the key features of each, you’ve come to the right place. As a company that has sold over 140.000 quality car parts, we’ll make things clearer for you. In this article, we’ll carefully analyze the differences between OEM, Aftermarket and used car parts. Let’s dig in!

What Are OEM Parts?

OEM is an acronym for Original Equipment Manufacturer. Just as the name implies, these car components are the authentic ones designed in the company by your car’s original manufacturer. Whenever your car parts need replacement, OEM guarantees that they’ll fully match those initially installed straight from the factory. They will work and look identical to the part you’re replacing.

To ensure that your replacement parts are real, just check the brand logo on the package. If it’s one of your manufacturers, you have an OEM. That’s why Mercedes-Benz is an official provider of Mercedes-Benz parts, Porsche is an official supplier of Porsche parts, and so forth.

What Are Aftermarket Parts?

Aftermarket parts are also known as alternative components. They aren’t sourced by the original car manufacturer but made by a third-party company. This market is crowded, as there is a vast array of aftermarket part producers. As a natural consequence, it is very competitive as well. All third-party companies have the same goal – to produce a part that bears the closest resemblance to OEM parts.

They should accurately emulate the original manufacturer in both aesthetic features and performance capabilities. We can easily find them in various categories. From replacement mechanical parts and performance upgrade parts to collision repair parts, the options are numerous.

What Are Used Auto Parts?

Used before and resold for goods, recycled car parts are quite a popular car replacement option. After all, there are many car parts where getting a used one is a smarter choice than investing in an official one. These include mirrors, headlights, wheels, and so on.

Undeservedly, they have an inaccurate reputation for lacking a specified origin and warranties, which is not the case. But this is only one part of the story. Let’s not forget that there are used OEM and aftermarket parts, too. What’s best, you may encounter some car shops that sell car parts that aren’t much used or almost brand-new.

A Plus Auto offers a broad set of top-quality used car parts that offer a cost-effective alternative to the more expensive proprietary components.

OEM vs. Aftermarket vs. Used Auto Parts: Where's the Difference?

Selecting quality car parts relies on careful inspection of various segments. To help you make informed decisions, we’ll break them down for you.

Cost

Among all three options, used car parts are the most cost-effective solution. When the car warranty is over, getting them saves money in the long run. But if you want more variety in pricing, consider the aftermarket parts. Their scope varies from low-priced to expensive high-end options. Still, no matter how well-made an aftermarket part is, it cannot outprice an OEM part. After all, they are the most expensive because of the guaranteed fit and first-rate quality that brings a piece of mind to their buyers.

Quality

Contrary to old-fashioned beliefs, the quality level of used car parts does not depend on the length of previous usage and the extent of care. Used OEM parts undergo the same testing and quality checks as OEM itself. In the case of aftermarket parts, the quality fluctuates. Some can be on the level of OEM, some are significantly lower, and a few are somewhere in between. That’s why some prefer the stability of OEM, which always produces car parts of the highest rank. They pass meticulous quality controls, and car manufacturers make the new replacement parts according to the original sketches.

Availability

Used car replacement parts are widely available. Even if you possess an old-timer or collect less common vehicles, you can still find a suitable solution. That being said, this aspect is the greatest edge over the rest replacement options. The aftermarket parts have an availability scope somewhat between used and OEM parts. Less available than used parts and more available than OEM, the aftermarket offers greater convenience. All you have to do is visit a local mechanic, store, or gas station, and you’ve found yourself a matching replacement part. But to order an OEM part, you’ll need to visit the authorized dealership and specialized car shops which are limited in number.

Compatibility

If you’re looking for a perfect fit, you can find that with OEM used car parts. Some companies like A Plus Auto offer such quality. When it comes to aftermarket parts, some are almost as good-fitting as OEM, yet some don’t fit well. It all comes down to how thoroughly you’ve selected the part. The highest precision is reserved for OEM parts. Not only does the new part fit ideally but it guarantees it will do its job in harmony with the old parts.

Use

Usually, used parts are best for old vehicles. It’s difficult and expensive to find a new part for them. But with their versatility and availability, there are quality used car parts for everyone. If you prioritize wide selection options, constant customization, and functional upgrades, the aftermarket gives you all of that. And if you satisfy yourself with premium-quality and durability only, OEM is the one for you.
