In the aftermarket auto parts industry, the word billet is tossed around an awful lot—and in plenty of different contexts too.

Sometimes it’s used to describe the sturdiness of a key bracket or housing, while in other instances you hear billet used to describe a slick-looking grille or accent piece. And sometimes, the word billet is flat-out used incorrectly in some odd context simply because it’s an appealing buzzword.
