The intercooler and piping is the last thing left on my install. . .I'm not quite sure how the ducting stays in place. I'm sure once it's all finished it will wedge in there pretty well, but are there any ways to really stabilize it in place?

 

There should be 2 screws on the sides of the IC that holds the duct.

 

I have the cool charge II and it just sits in there no screws. I can force it to shift around but have had no problem with it staying put once it's where I leave it.

 

I've been playing with it, and just like you mentioned. . .it should stay put. I think I'm going to modify the stock duct brace and put two holes to give it a little more stabilization. Should be pretty easy.
