CAI Problem, CAI Options

[fenderdave]

Hey,
Last night I finally did my first MOD on my 7AFE, (CAI) fitted the pipe, has a whole for the temp sensor, and one for a breather tube, but I closed this off as i had no where to put a breather tube.
My issue is that when i first start the car it makes a lot of noise like you can hear it sucking up the air and the rev's are about 600 higher than normal, then once the engine heats up it stops making the noise at the rev's drop back down.

I'm guessing this isn't normal? anyone got any ideas why its doing it?

thanks in advance.

I've just tightened all the clamps, checked everything, there's definitely no leaks, but its making a hell of a lot of noise (not in a good way) when i first start it up and still idles higher than it should/was. kind of like a sucking/hissing sound, from looking at it the induction kit seemed to be shaking around a lot as well. if im accelerating the noise goes away, but if im just cruising or stationary it comes back until the engines up to temp.

Is this normal? I'm far from an expert with engines but it just doesn't seem right to me. and doesn't sound good at all.

ONce the engines up to temp it sounds great and the rev's drop back down when idling.

Any thoughts, comments advice would be greatly appreciated
