Importance of Using Genuine OEM Parts on High Line Vehicles.

High line vehicles like Porsche, Audi, Volkswagen, Mercedes Benz, and Volvo are meticulously engineered to deliver exceptional performance and reliability. Using Genuine OEM (Original Equipment Manufacturer) parts is crucial for preserving the integrity and value of these vehicles.

Differences between OEM and Aftermarket Parts:

OE, OEM and OES mean basically the same thing. OE - Original Equipment, OEM - Original Equipment Manufacture and OES - Original Equipment Supplier mean just that, Original part that came on the car new. No vehicle manufactures make every part that comes on the vehicle, rather they will source out certain parts from different suppliers. But all these parts must meet the stringent specifications set forth by the vehicle manufacturer. They go through extensive testing before being branded an OEM part.

 OEM Parts:

  • Identical to the original parts installed on the vehicle. No modifications to make it fit. No compatibility issues. They work just like the part that is being replaced.

  • Meet the vehicle manufacturer's stringent specifications.

  • Undergo rigorous testing for performance and durability.

  • Parts are updated and/or improved if the vehicle manufacturer deems necessary.

  • Carry a warranty.

 Aftermarket Parts:

  • Manufactured by companies not affiliated with the vehicle manufacturer.

  • May not be designed or manufactured to the same specifications as OEM parts.

  • Can be of varying quality, materials, and incorrect fitment.

  • May not have undergone rigorous testing or updates.

  • Can have shorter warranties or no warranty at all.

When Aftermarket Parts Can Be Beneficial:

 Performance Enhancements: Some aftermarket parts are designed to improve performance beyond the original specifications, providing enthusiasts with increased power or handling.

 Flaws in OEM Parts: In rare cases, certain OEM parts have known flaws that have been addressed by aftermarket manufacturers.

 Cost Savings: Aftermarket parts can sometimes be less expensive than OEM parts, but it is important to consider the potential trade-offs in quality and durability.


For the ultimate peace of mind and to ensure your high line vehicle continues to perform at its best, it is highly recommended to prioritize the use of Genuine OEM parts. While aftermarket parts may offer certain benefits in specific situations, OEM parts remain the superior choice for maintaining the integrity, reliability, and value of your prized automobile.
