OEM Parts Explained

As we mentioned above, OEM stands for “Original Equipment Manufacturer”. Should your vehicle require replacement parts due to a mechanical breakdown or a collision, OEM replacement parts will be identical to those installed on your vehicle when it was initially built. As a result, you can also expect the exact same levels of performance and quality once the repair has been completed. In addition to an exact fit and finish, OEM parts typically carry a higher price tag compared to aftermarket parts. They can also be more difficult to find since they’re produced by the original manufacturer.

OEM Parts Advantages

  • Identical to the part that is being replaced
  • Generally include warranty coverage
  • You’ll know exactly what you’re getting

OEM Parts Disadvantages

  • Usually more expensive than aftermarket parts
  • Despite their higher cost, they’re not necessarily always of superior quality
  • Depending on the make/model of your vehicle, availability can potentially be limited

Aftermarket Parts Explained

Although they’re designed to look and operate just like OEM parts, aftermarket parts are produced by various different manufacturers. Aftermarket parts differ from OEM parts in several key areas including quality, pricing, and availability. As a general rule, aftermarket parts are usually less expensive than OEM parts. However, the quality and availability can be better or worse than OEM parts depending on who manufactures them. Sometimes, aftermarket parts can represent a tremendous bargain and be available on short notice for an unexpected repair. Other times, aftermarket parts can fail sooner and leave you stranded at the most inconvenient times. It’s important to do your research or ask our team of parts experts at your local Basil Family Dealership parts department for more in-depth information and advice regarding OEM vs aftermarket parts.

Aftermarket Parts Advantages

  • Typically less expensive compared to OEM parts
  • Generally more variety and more options to choose from
  • Usually more readily available

Aftermarket Parts Disadvantages

  • Quality can differ from manufacturer to manufacturer
  • May not include warranty coverage
  • Selection can be overwhelming at times

OEM Parts vs. Genuine Parts: Is There a Difference?

The terms OEM parts and genuine parts are often used together, but their exact meaning can depend on how a manufacturer, supplier, or seller uses the terms.

  • Genuine parts: Commonly sold in vehicle-manufacturer packaging through an authorized parts channel.
  • OEM parts: Commonly associated with the original manufacturer, original supplier, or the specifications used for the vehicle’s original component.
  • Aftermarket parts: Produced by independent manufacturers for use as replacement or upgraded components.

Because terminology can vary, verify the part number, manufacturer, vehicle application, warranty information, and seller before purchasing.

How Can You Identify the Correct OEM Part?

1. Use the VIN

A vehicle identification number can help a parts specialist narrow the search to the correct year, model, engine, trim, and configuration.

2. Confirm the Part Number

Compare the replacement part number with the vehicle application and any superseded part-number information.

3. Verify the Source

Review the manufacturer, packaging, seller, warranty terms, and return policy before ordering or installing a component.

What Should You Compare Before Choosing a Replacement Part?

  • Vehicle compatibility: Confirm the correct year, make, model, engine, trim, and equipment.
  • Part purpose: Consider whether the component affects safety, emissions, appearance, comfort, or routine maintenance.
  • Manufacturer and quality: Review the company that produced the part and its reputation for that specific component.
  • Warranty terms: Compare coverage length, limitations, installation requirements, and claim procedures.
  • Total repair cost: Consider the part price, labor, related components, and the potential cost of repeating the repair.
  • Availability: Confirm whether the correct component is in stock or must be ordered.

A qualified parts or service professional can help you evaluate the options for your specific vehicle and repair.
