Does blackening the grille require registration?

Blackening the grille does not require registration. Here is an introduction about the grille: 1. Meaning: The grille, also known as the car's front face, devil face, grid, or radiator grille, primarily serves to allow air intake for the radiator, engine, and air conditioning, preventing damage to internal components from external objects while driving and enhancing aesthetic appeal to showcase individuality. In automotive engineering, the grille is used to cover the body to allow air to enter. Most vehicles have a front grille to protect the radiator and engine. 2. Development: Various types of grilles have emerged. Since the late 1930s, Cadillac changed its style from a single-bar grille to various cross grilles, making the car look different year after year, hence there is no fixed form for the grille. Sometimes, the grille can also form a trend. For example, in the early post-World War II years, many American car manufacturers generally shifted to fewer but thicker grille bars.
