What are replacement components for vehicles not manufactured by the original manufacturer called?

Replacement components for vehicles that are not produced by the original manufacturer are classified as aftermarket parts. These parts are manufactured and sold by third-party companies and can include anything from performance upgrades to replacement pieces that meet or exceed the specifications of the original equipment.

Aftermarket parts offer vehicle owners a broader range of options when it comes to repairs and modifications, often at a lower price point than original equipment manufacturer (OEM) parts. They can vary widely in quality, price, and performance, catering to different needs, whether that’s affordability or enhanced performance. Understanding this distinction is vital for consumers who want to make informed decisions about their vehicle maintenance and modifications.
