Maz, it is a bit of an arse to fit, but the best way is to put the main part of box in by the rad, then undo the bend into the plenum and connect that to the top on the airbox. The bend gets squeezed together as your clipping the box back together. That was the easiest way for me to do it. Im no good with my hands an it took 10mins! Mine sits quite solidly without any restraining, its rests on the coolant hose and after a good 5000 miles i've seen no signs of wear to the hose.
Hope thats some help for you.
