Put an AEM Cold Air Intake into the '05 Denali with 124 K. Yes, they will make it louder when you punch it. However, that is not the case. It's when I am on the highway in 4th gear that it is just annoying as hell. It's so dam loud, can't even have a conversation. If i punch the accelerator, and drop the transmission down into third, much quieter. But that should be when it's louder, pushing a lot more air through it.
Have had Cold Air intakes before. Something is not right here.
