An aftermarket part is any part for a vehicle that’s not sourced from the vendor or cars maker. These, in some cases, can alter or even void the existing warranty you have on your car. Some companies create aftermarket parts that function the same as the preexisting part, and sometimes they can alter the way your car operates. The goal with an altered part is for either curb appeal or to improve the way your vehicle operates. These differ from Original Equipment Manufacturer parts specifically because they’re not created by the same vendor.
Aftermarket parts have many pros such as being less expensive than OEM, there’s a larger variety available, and you can pick them up at any parts store or the local mechanic in your area. While all of this is appealing if you know the ins and outs of the part, you’re also facing quite a few reasons you wouldn’t want an aftermarket part. They can be inferior parts because they’re not regulated the same way as OEM parts. You’re literally “getting what you pay for” because the cheaper they are, the more likely they are to be lower quality. That doesn’t always ring true, but in this case you have a higher chance of finding a poor quality part as opposed to purchasing directly from your dealership. There’s also a ridiculous amount of parts available in today’s market, so unless you’re familiar with a specific vendor, it can be hard to make a choice. These parts also don’t often come with a warranty, which is part of why they are so cost effective.
On the other hand, a remanufactured part is a part that was completely remanufactured to the standards set by the vehicle manufacturer. This process can be performed in many different ways, but often includes re-machining the part to match the original tolerances, durability and quality. They include a warranty, which cover the part and labor for longer periods of time than you’d find with an aftermarket parts. These are commonly preferred over aftermarket, but you’re going to find ones that match your vehicles specifics as opposed to finding ones that add flare to your vehicle.
In the long run, if you have questions about the type of parts you should use on your repair, it’s always a good idea to ask a professional.
