OEM vs Aftermarket Parts – Worth the Extra $$$?

Original Equipment Manufacturer (OEM) automobile parts are made by the manufacturer your vehicle while aftermarket parts are not.  Generally, OEM parts cost more.  Are OEM parts worth the extra money?  Following are some facts that will help you to make a more informed decision.

Aftermarket Parts Pros & Cons:

The term “aftermarket” refers to any part not manufactured by the vehicle’s maker or manufacturer.  Many companies manufacture parts that are designed and intended to function the same as OEM parts.  In some cases, the aftermarket parts are even better than the original.


  • Availability – Aftermarket vehicle parts are more readily available thus decreasing the time it will take for a mechanic to get to work on your vehicle.  They can be sourced from many places and depending on your locale, are often available locally.
  • Quality – High-quality aftermarket part manufacturers can’t just pick up a blueprint and recreate the part.  They must reverse-engineer the part and, during that process, can make needed improvements or take advantage of chances to save costs and pass those savings’ on to consumers.
  • Price – Prices will vary by brand but often, aftermarket parts are less expensive than the OEM equivalents. This price variation means that you need to shop around.  Be prepared to also ask questions about the quality of the part.


  • Warranty – OEM parts typically come with generous warranties.  Aftermarket parts manufacturers may not offer the same warranty, if any, in the effort to economize.
  • Quality – Some inexpensive aftermarket parts can be inferior in quality due to using lesser quality materials.  It is best to stick to familiar brands and check with your auto repair shop for a professional opinion.
  • Selection – The vast selection of parts can be overwhelming for a consumer unfamiliar with aftermarket parts manufacturers.  The greater the number of choices, the higher the chance is that there could be slight variations from part to part.
OEM Parts Pros & Cons:

OEM parts are identical to the parts that came with your vehicle when it was brand new.


  • Ease of choice – Since there is only one choice for any given part, there is no need for any research to assess and compare the quality of different brands.
  • Quality – It is almost a certainty that an OEM part will perform exactly as the part it replaces.
  • Warranty – Most OEM parts are sold with a warranty for at least one year.  An auto repair shop that uses OEM parts is more likely to “warranty” the labor.


  • Price – OEM parts are generally more expensive.
  • Availability – OEM parts come directly from the manufacturer and usually purchased through a dealership.  If a part is out stock at the dealership, it will need to be ordered and shipped.  This will add time to your repair.

The best answer, in any situation, is to consult with your service provider.  In the case of body parts and collision repair, the technician will likely prefer OEM parts to be assured of the proper fit and performance.  Mechanical repairs should be taken on a case-by- case basis.

The pros at Shepard’s Automotive Center value customer relationships and we seek to be your one-stop-shop for mechanical and collision repair.  We invite you to contact us and, regardless of your repair, we will be happy to work with you to map out a plan that fits your budget and solves your problems.
