I recently installed my AEM CAI and the first time I started her up I heard this ugly whistle. Well at least thats what i called it in the last post, "a whistle." But it is getting so fucking worse. It is more of a nasty hiss and sometimes its much louder thatn other times. It is so loud now especialy on oldewr days. Everything is connected just fine. At first I thought there was something like a loose hose or air seeping in somewhere but that wasnt it. Does the filter come oiled already, for some reason I think that might help. I connected one hose from the intake to valve cover like the directions says but there is a second tube lower down the tubing that can either be capped or as the direcions say "is used for some california vehicles due to some state emissions code" or something, well I have a california car, I capped the hole should I not have?
