Well, what i did is shove the lid into the hole. If you try it, you will see that it fits pretty snug and if I remember correctly, It already has a clamp on there. I'm doing my own intake mod right now. I am in the process of removing the airbox (the black box with the 2200 writing on it) and using 3" plumbing tubes to make a shorter, less winding intake. I'll take pics when I can.
