after thinking about it i beleive it would be possible to pay a metal fabricator to make a piece out of alum to replace the stock plastic piece. it can be made to flush mount with the bumper instead of sticking out the 3mm or so. i would ask for it to be an inch shorter height wise so that the bottom air inlet is larger. i would buy some of the black pastic mesh from mazda and cut out an inch to align with the mesh already there. then new alum piece would be painted to match car color.
i used paint (crap quality) to give an idea of what i had in mind. i gave the new top piece a slight curve where it meets the mesh, inspired by the speed6. i also have the grille, fog lamp surrounds painted gunmetal to match the factory painted wheels, inspired by the accolade body kit. i also have the lower portion of the side sill extensions coated with rhino lining (or some other spray on plastic) to prevent the noise loose stones make and to make the front treatment more cohesive. any suggestions, or thoughts?
