Everyone always posted one of the main reasons they did not like the MAC CAI was it was metal and got hot which then made the pipe a hot air intake and not cold like it was supposed to be. What is the difference with the C&L inlet tube? It is also metal. I did the mod to rotate my MAF and wrapped my MAC CAI with header tape and have had no problems and I like it. Waht is the difference? They are both metal.
