Are non genuine car parts OK?

No, using non-genuine car parts is generally not recommended. Genuine or original equipment manufacturer (OEM) parts are designed and manufactured specifically for your vehicle, ensuring a proper fit and optimal performance. Non-genuine parts, on the other hand, may not meet the same quality standards and could potentially cause issues with your car's operation, safety, and longevity.


Understanding the Risks of Non-Genuine Car Parts


While non-genuine car parts may be cheaper upfront, they often come with a higher risk of problems down the line. These parts may not be made to the same specifications as the original components, leading to compatibility issues, reduced performance, and even safety concerns. Additionally, the use of non-genuine parts may void your vehicle's warranty, leaving you responsible for any resulting damage or malfunctions.


Potential Issues with Non-Genuine Car Parts



  • Compatibility problems: Non-genuine parts may not fit your vehicle properly, leading to issues with installation and potential damage to other components.

  • Reduced performance: Non-genuine parts may not perform as well as the original components, resulting in decreased fuel efficiency, power, or handling.

  • Safety concerns: Substandard parts could compromise the safety features of your vehicle, putting you and your passengers at risk.

  • Voided warranty: Using non-genuine parts may invalidate your vehicle's warranty, leaving you responsible for any resulting repairs or replacements.

  • Decreased longevity: Non-genuine parts may have a shorter lifespan than OEM components, leading to more frequent replacements and higher long-term costs.


While there may be some instances where non-genuine parts are acceptable, it is generally recommended to use genuine or OEM parts for your vehicle to ensure optimal performance, safety, and longevity.

What do you call parts that are not OEM?
