Air box is done having a air box eliminator bracket made as well. Turned out pretty good for $40, still need to have the outlet flange welded on once my motor and card are mounted and I know where it needs to be. Box easily fits 9" k&n filter and is easily removable with the box in place it will get a cover of outterwears fabric for a lid and will only be used when I trail ride. Gonna buy a second 9" k&n for my air box eliminator bracket that will be used when I drag race.
