There's also the PDM intake, or you can spend $20-30 and make one that draws from the fender yourself. Of course, if you DIY, it's not anywhere close to as nice looking as the Ganzflow. ;]
TMRRally, what do you think yours will cost? (sorry if this was covered somewhere else, that's the first i've seen of that intake). I would _love_ to be able to actually use my hood scoop finally. Especially if the RS is thrown out of STS for autocross, hehe.
