AfterMarket vs OEM

At some point in the life of your vehicle, you will likely need to replace some part or component. Most people believe they must use a genuine part or they will void their warranty and are given that impression. This is simply not the case. The FTC stepped in and issued a consumer alert stating "The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you sued an aftermarket or recycled part". Also, you cannot void your warranty by having maintenance or repairs done somewhere other than the dealership, or even by doing them yourself. Hopefully after understanding the drawback and benefits of various types of parts, it will help every car owner decide which is the best part for their vehicle.

Understanding the Different Types of Parts

When a part fails on your vehicle and needs to be replaced what type of replacement part offers the best value and quality? Knowing the different types of parts available will help you select the proper type and can save you money.


A Genuine part, is the part that was originally put in your car when it was new. It comes in a box with the automaker's logo on it. However, it was actually made by another company. These parts are the most expensive.


OEM stands for Original Equipment Manufacturer. It is the exact same part that came in your car built by the same company that originally made it for your car, minus the automaker's logo on it.


Aftermarket parts are made by a company other than the original manufacturer. These parts perform as well as, and sometimes even better than OEM parts because companies reverse-engineer the parts and work the weaknesses out. They are usually less expensive than OEM parts. Beware, they are not all created equal. Do your research.

Rebuilt or Remanufactured

A rebuilt or remanufactured part is basically a used part that was completely taken apart, fitted with new parts and tested. A part usually fails because a of a few internal parts that wear. The rest of the part is fine. Rebuilt parts are a great value and will perform the same and last just as long as the original.

Refurbished or Reconditioned

Refurbished or reconditioned parts are used parts that have been cleaned and maybe a few external parts like nuts, bolts or gaskets replaced. Although they are used parts and do have some level of wear, they are inexpensive compared to new parts.

Used or Recycled

Used or recycled parts are just that. They are the least expensive and will not last as long as a new or rebuilt part. A used part should never be chosen when it comes to safety. This would include any brake, steering or suspension part.

What Type of Part Should I Use?

Genuine - Only choose if it's still under warranty and you don't have to pay for it. There is no sense paying extra for a logo.

OEM - If your car is less than 3-4 years old and the part is not covered under your warranty. You'll get the exact same part originally installed for a better price than the genuine price.

Aftermarket - If your car is older than 3-4 years, an aftermarket part is the better choice. It is less expensive and may perform even better than the original.

Rebuilt or Remanufactured - If your car is older and has higher miles, rebuilt parts are a good option if you plan on keeping your vehicle. You'll never get your value back out of it.

Refurbished or Reconditioned - If your car is older and you don't plan on keeping it, refurbished is a good option.

Used or Recycled - same as refurbished. Also good for parts that don't wear i.e. door handles, trim, glass, molding or body parts.

Ultimately, whether you decide to go with OEM or Aftermarket parts it's important to find an auto body shop that you know and trust. At One Stop Auto Parts & Service Center we can assure you that we use the right parts and components for your specific vehicle; regardless of make and model.
