I covered the fake vents. I used plexiglass. I cut the pieces to shape, then I heated them with a heat gun at the 1100 degree setting. When the plastic was soft and bendible, I placed each piece over the bumper to form the curves of the bumper. When the piece cooled enough, I set it aside to fully cool. Then I spray painted them semi-gloss black. I attached them to the bumper using double back foam tape.
