When shopping for car parts, you’ll often see the term OEM. But what exactly does it mean, and how does it compare to aftermarket options? If you’re buying from a junkyard or self-service yard like a U-Pull-It facility, understanding OEM is key to getting the right fit and performance.
What Does OEM Mean in Car Parts?
OEM stands for Original Equipment Manufacturer. These parts are made to the exact specifications as the ones that originally came with your vehicle when it left the factory.
- Exact fit and performance — Designed to work perfectly with your make and model.
- Factory quality — Meets the same safety and durability standards as the original part.
- Branding — Often stamped with the automaker’s logo or part number.
Example: A brake disc made for a 2018 Honda Civic by Bosch for Honda is an OEM part — even if Bosch also sells a similar version under its own name in the aftermarket.
OEM vs. Aftermarket: Key Differences
| Feature | OEM Parts | Aftermarket Parts |
|---|---|---|
| Fit | Exact match | May vary slightly |
| Quality | Factory standard | Quality varies widely |
| Price | Higher | Usually lower |
| Availability | Dealer, OEM suppliers, salvage yards | Auto parts stores, online |
| Branding | Automaker or OEM manufacturer | Parts brand name |

Are OEM Parts Always Made by the Automaker?
Not necessarily. Automakers often outsource parts to specialized manufacturers. For example:
- Denso makes many OEM Toyota components.
- Bosch produces OEM brake and electrical parts for multiple brands.
The key is that these parts meet the exact factory specs.
How to Identify OEM Brake Discs and Other Parts
Look for these signs when inspecting parts — whether at a dealer, parts store, or junkyard:
- Automaker logo or part number etched or stamped.
- Original packaging (if buying new).
- Certifications such as ISO or SAE compliance.
- Matching wear patterns when replacing in pairs or sets.
If you’re sourcing from a salvage yard, check our junkyard buying tips for inspection advice.
Can OEM Brake Discs Be Replaced with Non-Original Parts?
Yes — many aftermarket brake discs meet or exceed OEM standards. However:
- For safety-critical parts like brakes or airbags, OEM is generally the safest choice.
- For restoration projects or maintaining warranty coverage, OEM is often required.

Do Junkyards Provide Only OEM Parts?
Most vehicles in junkyards still have their original OEM parts. That’s because:
- Many cars arrive with their factory-installed components intact.
- Aftermarket replacements are less common on non-modified vehicles.
You might also find aftermarket upgrades, especially in wheels, stereos, and exhaust systems.
