After-Market Parts Key Terms

Learn the words commonly associated with after-market parts

By Shannon Tani

After-market auto parts are anything that a consumer purchases for a car after the initial purchase. This could mean parts for repair but also means accessories or modifications that the consumer wants. If you need to get into the after-market industry, there are a number of key terms that you should know. You wouldn't want to confuse a body kit with a turbo kit, for example, or try to sell after-market parts to a customer who wants only OEM parts.

Body kit

A body kit is used to make modifications to the appearance of a car's body. These could include fender flairs or hood scoops, for example.

Turbo kit

A turbo kit blows more air into the engine so that it is able to perform better. A car with a turbo kit has more "power," but it's important to make sure that the car has the type of engine to support the extra power burst.

Original equipment manufacturer (OEM) versus after-market parts

Original equipment manufacturer (OEM) parts are, like the name implies, parts that are made by the original manufacturer. After-market parts are made by a different company, but are designed to fit and act like OEM parts. After-market parts are often less expensive.

"Right to repair"

The "right to repair" has become a significant issue recently. Some automobiles require the owner to use the dealer's or manufacturer's repair services, which are often more expensive than other mechanics. This has led to a right-to-repair movement, promoting the idea that consumers should be able to choose when and where they repair their vehicles.
