Once again, eRam is crap. Do some research. It only works at WOT, and even then it will most likely rob power. Every car forum on the internet bashes this thing. I challenge you to find another car forum where these things are embraced as a legitimate power mod, or anyone in a car forum that states that he is happy with one. What kind of CAI do you currently have? If it is not a NeedsWing CAI, then that is where you would be better off spending your money. Lots of smart people on here. If even one of these smart people thought that eRam was worth anything, they would have spoken up and helped you with your question. Some of the smartest people on the forum have already replied to this post by mocking you for even considering putting a piece of crap like that on your car. But hey, if you think that you are smarter than everyone here... Shell out your hard earned money on this junk, and get you a coffee can muffler while you are at it. At least all the ricers will think it is fast by the sound coming out of the exhaust.
