Holy shit....alright so i have seen that there is a group buy goin on for hotshot CAI..let me start off by telling you that this thing screams!! once i put it in second gear and step on it, you can hear it from blocks away (lol tryed it). if you like the AEM intake sound from a honda this is it for the nissan, like an exact replica. for those of you in the group buy, its worth every penny and more...very nice power gain too. for those of you not in the group buy....buy hotshot CAI!
