I cant remember exactly if you have to remove the metal spring clips from the old airbox or the old airtubes when you replace them with the carbon items.....it was a few years ago when I fitted both carbon airbox and tubes....
He, he quite funy reallly coz now you dont know whether youll need a drill, a 3 or 4 mil drillbit, a pop-rivet gun and four pop-rivets (or is that 8 pop rivets)!!
