Automotive aftermarket meaning:
Aftermarket parts can be OEM replacement parts made by the OEM, or aftermarket including performance and accessories. Click To TweetVehicle parts and accessories may or may not be manufactured by the OEM. Aftermarket parts are divided into three categories: OEM replacement parts made by the OEM, aftermarket parts including performance parts for modification, and accessories.
OEM replacement parts are vehicle parts manufactured or re-manufactured (or “re-manned”) to replace OEM parts as they wear due to normal wear & tear of a vehicle, or for replacement due to damage. Aftermarket parts can be parts intended to be an alternative to OEM replacement parts, or can be an aftermarket part with different specifications altogether, and can be an add-on part or can be intended to replace an existing part. Accessories are parts made for the vehicle owner’s comfort, convenience or safety, or for customizing the vehicle, and are typically add-on parts. These can be after the original sale of the motor vehicle or they can be accessories installed by the automobile dealer.
