The term 'AUTO GRILLE PROTECTOR' is a job description for a BRA, which stands for 'Brush Guard'. A Brush Guard is a protective device that is installed on the front of a vehicle to protect the grille from damage. It is typically made of metal or plastic and is designed to absorb impacts from rocks, debris, and other objects that may be thrown up by the vehicle's tires. The Brush Guard also helps to reduce wind resistance and improve aerodynamics.
