Yea dude get that and also at Pep Boys there is this kit which is a tube that you attach to the top of the cone with an additional connect and it allows you to make a "ram air" setup. I just saw it yesterday and want it bad but I dont know how much it is. That small connect was $9 alone so Im assuming this tube would be $20 at the least. The top of your cone has to be inverted though in order to do this. You should also get some sort of a heatshield built around it to be most effective.
EDIT: I swear the two words "connect" were supposed to be "connector" and I know I spelled it right!!!
