it was a biotch to fit in, but eventually got it. plus its thicker, looks way better and comes with the adapter for whatever carb, airfilter and outerwears screen lid.looks alot nicer.
the cfm fits right in perfectly, nothing to fight. it also comes with the carb adapter and you can get either a uni or k&n filter for it. I don't think that the pb airbox is any thicker. the cfm box is pretty thick and it features the regular aluminum look, instead of having the hologram look or whatever pb calls it. the cfm box is also cheaper and when i ordered mine, i emailed cfm and got the airbox and the air scoops and shipped to my door for the same price as the pb airbox
