The black brace came with the adapter kit. I figured I'd use it to support the filter by mounting it to the side of the inside fender. I wouldn't have used anything but it looked like a little more support wouldn't hurt. The filter lays on the bracket. The mass air bracket i didnt use. This is what the other bracket looks like.
