The invention provides a grille for a radiator cover having a front end with a pair of air intake apertures formed therewithin, and a pair of bezel frames each fastened to such radiator cover adjacent a respective one of such pair of air intake apertures, each bezel frame having an aperture exposing such respective air intake aperture. The grille includes a unitary elongated member having each of a predetermined size and a predetermined shape and a paper-thin like peripheral edge surrounding the unitary member. The member is caged between the bezel frame and the front end of the radiator cover. A plurality of apertures are formed in the unitary member for enabling air flow and for preventing entry of a detrimental extraneous foreign material into each air intake opening.
