not too much you. i was looking and i saw a kenne bell ram air front air damn and it had a scoop for the itnercooler also built into it. it looked pretty sweet. but i cna't even find where i can order one from
You can get that scoop from KB. I have it on my GN Picture at www.Johnhordych.com Don't use the ram air tho. Got a Big Mouth cold air set up. Much better than the ram air. http://www.buickgn.com/ For the cold air.
I bought it about 4 years ago. I don't remember the exact cost. I think around 200. If you get the scoop don't get the ram air intake, go with the cold air intake, like the one I have from http://www.buickgn.com/
The scoop is all one piece bolts up under bumper Fitment is very good.
