[McManuel]

The differences between OEM and aftermarket auto parts are: 1. Quality varies: OEM parts have superior quality with no issues in appearance or performance, but their prices are correspondingly higher; while aftermarket parts vary in price, and their quality is naturally inconsistent. 2. Presence of logo: OEM parts are usually secondary parts suppliers designated by the automaker. To distinguish them from aftermarket parts, they generally bear the logo of the automaker or the automaker's supplier. Relevant information about OEM and aftermarket parts is as follows: 1. OEM parts: Generally refer to parts assembled by the automaker's designated suppliers. 2. Aftermarket parts: If other manufacturers not among the designated suppliers or dealers also produce parts for the same vehicle model, they can be considered aftermarket.
