Why Buy OEM Vehicle Parts Over Aftermarket Products

Purchasing OEM Parts vs. Aftermarket Parts 

⏲️ 3-minute Read

All vehicle owners need to make decisions regarding vehicle maintenance. When it comes to this, choosing between Original Equipment Manufacturer (OEM) parts and aftermarket alternatives is crucial. While aftermarket parts may seem cost-effective, they often come with trade-offs that can impact your vehicle’s performance, reliability, and warranty coverage.  

OEM parts ensure a perfect fit, optimal performance, and long-term value, making them a better investment. In this blog, our team at Stony Plain Chrysler in Stony Plain, AB, explores why OEM parts are superior to aftermarket products, highlighting key factors such as cost, reliability, warranty protection, and overall convenience. 



OEM Parts vs. Aftermarket – A Quick Glance

  • OEM parts are made by the original manufacturer of your vehicle, ensuring a perfect fit and optimal performance.
  • Aftermarket parts are produced by third-party manufacturers and can vary widely in quality and compatibility.
  • While aftermarket parts are often cheaper, they may lead to more frequent replacements and potential compatibility issues.
  • OEM parts offer greater reliability and are designed to meet your vehicle’s specifications.
  • Using OEM parts helps maintain your vehicle’s warranty, while aftermarket parts may void it.
  • OEM parts typically come with warranties, providing additional protection and peace of mind.
  • Choosing OEM parts saves time and money in the long run by avoiding the hidden costs associated with aftermarket parts.

Understanding OEM Parts 

OEM (Original Equipment Manufacturer) parts are components made by the original manufacturer of your vehicle. For example, if you drive a Dodge, Ram, or Jeep, OEM parts are those manufactured by these brands. It also extends to a supplier contracted by them. These parts are identical to the ones your vehicle was originally built with, ensuring a perfect fit and optimal performance. The vital advantage of OEM parts is their consistency and quality, as they are manufactured to meet the exact specifications of your vehicle.

What Are Aftermarket Parts? 

On the other hand, aftermarket parts are made by external third-party manufacturers not affiliated with the original vehicle manufacturer. These parts are designed to function similarly to OEM parts but can vary significantly in quality, compatibility, and price. While aftermarket parts might be cheaper, they often come with trade-offs that can impact your vehicle’s performance and longevity. 

The Cost Factor: Is Cheaper Always Better? 

One of the primary reasons drivers buy aftermarket parts is the lower cost. Aftermarket parts are typically less expensive than OEM parts. This makes them an attractive option for those looking to save money on repairs. However, it’s essential to consider the long-term implications of this decision. While you might save money upfront, aftermarket parts can lead to more frequent replacements, potential compatibility issues, and even costly repairs down the line. 

When comparing OEM parts to aftermarket options, it’s essential to recognize that OEM parts are specifically designed for your vehicle. This means they’re more likely to perform better and last longer, saving you money in the long run. As the saying goes, “You get what you pay for,” this certainly applies when choosing between OEM parts and aftermarket alternatives.

Reliability and Performance: The OEM Advantage 

One of the most significant advantages of OEM parts is their reliability. Since OEM parts are made to the specifications of your car, you can trust that they will fit and function as intended. This is essential for critical components like brakes, engines, and suspension systems. 

In contrast, aftermarket parts can vary widely in quality. While some aftermarket manufacturers produce high-quality parts, others may cut corners to keep costs down. This can result in parts that don’t fit as well, wear out faster, or even fail prematurely.

Regarding your vehicle’s performance and safety, OEM parts are better than aftermarket options, offering peace of mind that your car will operate as it should. 

Warranty Considerations: Protecting Your Investment 

Another important factor to keep in mind when choosing between OEM and aftermarket parts is your car’s warranty. Many car manufacturers require that you use OEM parts for repairs to maintain your warranty coverage. If you opt for aftermarket parts, you risk your warranty, which could leave you responsible for any future repairs. 

OEM parts often come with warranties, adding an extra layer of protection. So, if an OEM part fails, you can repair or replace it at no additional cost. In contrast, aftermarket parts may not come with any warranty, or the coverage might be limited if they do. When considering the potential long-term costs, OEM parts are better than aftermarket alternatives, especially if you want to keep your warranty intact. 

Time and Convenience: The Hidden Costs of Aftermarket Parts 

While aftermarket parts might be readily available and offer faster shipping options, this convenience can come at a price. OEM parts are tailor-made for your vehicle, ensuring a perfect fit and reliable performance. In contrast, aftermarket parts may require modifications or adjustments, leading to longer installation times and potential delays. 

Moreover, if an aftermarket part fails or doesn’t work as expected, you may need to spend additional time and money replacing it. This can negate any time or cost savings you initially enjoyed. By choosing OEM parts, you’re investing in quality and reliability, saving you time, money, and headaches in the long run.
