Intake vacuum line question

Intake vacuum line question
Non turbo but I figured you guys would know since most cold side intercooler piping is straight into the manifold.
Doing a true cold air intake (rerouting the AFM/MAF) so that it never crosses in front of the engine where hot air can be absorbed. However, on the OEM intake piping before the maf, there are three hoses, all of which I assume are just vacuum lines. Is it common to just plug these off and not have a second thought or do I need to continue trying to figure out how to have the piping and maintain these hose connections.

<p>Left side is idle valve. Right side is a resonator or something I think. Middle is crank case ventilation. You need all of them if running stock ecu. Maybe not the resonator thing.</p>

<p>Idle valve 100% needs to be there. Resonator pipe will be gone when you remove the stock intake. You should have seen that already. Aren't you turboing? So you will have an ECU anyways.</p>
