ummm you ever felt your metal CAI tube after a long drive or some hard pulls, if you so wont think that way anymore, Ive seen many where you can barely touch the tube after a good run, heat IS an issue with CAI's thats why I have an ICEMAN and I love it, and I guarantee better gains over the AEM (AEM your just paying for the name) well iceman too but iceman tube is plastic and much better at keeping intake air cool
