Cold air/short ram vacuum line?

For those that have either a cold air or short ram intake (preferably on a 92 Si), do you have both factory vacuum lines attached to the new intake?

^^What is the butterfly valve thing? Does it go in effect after 4k rpm? I've heard that name before but never found out what it is or does.

^^ From what I remember the resonator has a flap that is connected to it. After 4K RPMs or so it opens.

Are there any tricks to removing these?
Looked in the Chilton manual I have and it only showed these in the vacuum diagram. Nothing mentioned how to get to it or remove it.

it's a huge pain to get the resonator out. If I remember right there is a bolt from on top (under where the filter used to be), one from underneath the car, and then an evil one that you can only get to by removing the bumper or removing the turn signal and sticking a wrench in through there. I recommend getting the helms service manual if you plan on doing your own repairs in the future.

As for the lines, I plugged the one going to the resonator at the IM and left the other one open.

Where should I look for a breather filter for the valve cover and what size do I need?

Ok, let's just get this straight - earlier you were referring to the two vacuum lines that come off the IM right?

Now you want to disconnect the line from the intake to the valve cover. I'd say just leave it hooked up but if you want a breather you can get one from any pep boys type place. You just need a small one. They are about two inches in diameter and have a worm clamp. I believe the tube you're try to put it over is 3/8.

Looks like this:

I want to keep the air boost valve connected. Since the short ram only has one vacuum connection thats what I'll keep. So the breather filter is for the valve cover.

Does that make sense?

"Air-Boost Valve", I'm assuming refers to the resonator valve. With an aftermarket intake... this valve has no use whatsoever since it is a component of the stock intake system.

This is not true, I was able to get everything out by just pulling back the fender lining... took about an hour but I got everything out.. I just yanked out the box mounted near the strut tower to... not needed anymore!

No thats not it.
This is a vacuum diaphragm pump looking thing mounted on the valve cover side of the intake manifold and is plumbed into the intake air pipe.

This isn't the resonator. Thats located under the factory air filter in the wheel well.

That looked a little risky to me in terms of bending the bumper and/or cracking paint. But maybe you have smaller hands than I. A friend would help in that department too but I didn't have any at the time!

65coupe: yah that makes sense if you want it set up that way.
