if your really interested in this... make a homemade one first, before u spend $300 on it... go get a fan and wire it to run at WOT... made not that easy, but better than spending $300...
main concern with either setup (eram or homemade)... what happens if something breaks in the fan and piece gets sucked into TB
I have seen similar product and they seem to be a farse... if they really worked won't they be common like CAI...
if you want to take a shot it, go for it... let us know hoe it goes!!!
