What does that black plastic box that is between the induction tubing and the Inlet Air Control do? Is it just a resonator to cut down on noise, or is it some sort of filter? Can I remove it and just run straight hose? I see where it can be taken apart but am hesitant to do so in case it won't go back together.

Thanks!

Dont listen to the WRX man

Its a box to tone down the whistle at idle the IAC makes....or so I have heard. Take the hose off from where it connects to the IAC and fire her up just for fun...im not kidding, the car sounds like it has a very large cam! Friend of mine at a local meetup just did this to his GT (stock cams) and it literly would put mine to shame....actually sounded very good. Ofcourse you cant run around like that, but its fun to try

As long as by "filter" you mean noise filter, because otherwise, it filters nothing else. That baby is completely hollow inside.

A buddy of mine removed his & plugged the hole up. I could see that stupid box confusing the intake air & robbing a little HP, & its ugly. Im glad I have a C&L.

I am still not understanding what hole he plugged. If you remove the Black box, you need to run a longer piece of hose, there is nothing to block off.

A longer hose to what? . He plugged the hole where the box was connected. That box has no hose. Here look at this pic...

You are talking about the wrong thing my friend. We aren't talking about an Air inlet Silencer. We are talking about the little black box connected inline with the IAC (Idle Air Controller)
