What defines aftermarket parts in vehicle repair?

Aftermarket parts are typically defined as parts that are not made by the original equipment manufacturers (OEM). Instead, they are produced by third-party companies and are designed to replace the original parts of a vehicle. This category includes non-OEM replacement parts that can serve various purposes in vehicle repair, particularly for non-mechanical expenditures.

When considering the definition provided, these parts can vary in quality and performance compared to OEM parts but are generally intended to offer a more cost-effective solution for vehicle repairs. Aftermarket parts can be used to restore a vehicle's function after damage or wear, often appealing to consumers seeking less expensive options.

In contrast to the other definitions provided, aftermarket parts do not exclusively improve vehicle performance, serve only non-mechanical expenditures, or are limited to high-end vehicles. This broad applicability in terms of replacement and functionality is what makes them a popular choice in the repair industry.
