rubber accordian tube for intake
i had to ship mine off. so currently im running a short ram attached straight to the throttle body. attached with... duct tape. 
its attached well, but the three hoses that attach to the accordian i taped off with duct tape. so it runs. but it makes high pitched noises.
how important are those hoses? and until i can get my aem, is it ok to leave them capped? or should i get little air filters at autozone to attach to them?

The high pitch noise if probably coming from the oil breather hose.
I recall someone posted a video with it.
2nd hose goes to the intake manifold.
There are two "tubes" that extended into the engine where the primary intake runners are.
My belief is that this is to relief pressure in the block (correct me if I'm wrong).
3rd hose goes to a manifold for the VDI, SSV, and AIR solenoid.
This might be the most important to have since it needs vacuum to actuate the valves.

I disagree with Nem, here, because in the OEM orientation the three big hoses are only vents and not actual vacuum sources, nor are they seeking vacuum. They are actually controlled/metered vacuum "leaks". If you were to manifold them together the vacuum would render the jet-air and OMP nozzles useless as they need to see atmospheric pressure in order to work best. If you apply equal vacuum levels on both sides things may not work so swell.
Note to self: Never post in the Tech Garage unless you are absolutely correct.

I'm out in the garage looking at the setup again. That whole accordion tube is weird. I busted one of those cheap plastic elbows the other day, and improvised a temp until I got one from Jason for $5.65 each. Must be really nice plastic at those prices - LOL
