Erstausrüstungsbauteil

An Erstausrüstungsbauteil, often abbreviated as EAB or OE-Teil (Original Equipment part), is a component manufactured by a company that supplies parts directly to the original vehicle manufacturer for installation during the vehicle's production. These parts are identical in specification and quality to those fitted to the vehicle when it leaves the factory. They are produced according to the vehicle manufacturer's design and quality standards.

When a vehicle requires a replacement part, an Erstausrüstungsbauteil is the part that was originally installed in the vehicle. These parts are typically sold through the vehicle manufacturer's authorized dealer network or through authorized parts suppliers. They are generally considered the highest quality replacement option due to their direct lineage to the original component.

The term distinguishes these parts from aftermarket parts, which are manufactured by companies other than the original equipment manufacturer. While aftermarket parts can be of good quality and are often more affordable, they are not produced under the direct supervision or exact specifications of the vehicle manufacturer. Erstausrüstungsbauteile are designed for perfect fit, performance, and durability, ensuring the vehicle operates as intended by its manufacturer.
