Is the quality of genuine parts the same as OEM parts?
2 Answers
Genuine parts and OEM parts are not the same in quality. Here are the relevant details: OEM parts: OEM parts are generally products ordered by automobile manufacturers from parts suppliers. These products will have the manufacturer's brand printed on the surface. Since OEM parts are ordered by automobile manufacturers, their compatibility and quality are relatively guaranteed, but they are difficult to find in the market. Genuine parts: Genuine parts refer to products produced by parts suppliers under their own brands. These products will not have any automobile manufacturer's brand markings on the surface, only the logo of the parts supplier. Although they are the same in performance and specifications as OEM parts, they may not be as good in compatibility as OEM parts.
I happen to have researched this. Genuine parts and OEM parts sound similar, but there are significant differences. OEM parts are directly authorized by the car brand for production, with the brand logo on the packaging, and the production line is identical to that of the main factory. Genuine parts, although produced by reputable manufacturers and certified for quality, are third-party accessories with slightly looser standards. For example, for the same headlight housing, OEM parts might use higher-grade UV-resistant plastic, while genuine parts might use standard material. Price-wise, genuine parts can be 20-30% cheaper, which is sufficient for minor repairs. However, for core components like engines and transmissions, it's advisable to go for OEM parts despite the higher cost, as the fit and precision are far superior. The last thing we want during repairs is gaps or strange noises after installation—OEM parts eliminate such worries.
