Interesting Question

Tube

Take your tube out and look at it. There is little to no opening to get air into it. It is in now way beneficial to performance. It weighs a ton for being a black plastic box. If you dont want to do a full cold air intake, get a short ram intake, then if you feel like doing this and getting a little more out of it. Fabricate a box around your filter. Using your choice of tubing, Oreilleys has a good option, connect the box to the hole by the battery. You will get close to the same effect as a cold air, but with out the water intake issues. Minimal as they are. Or if you really wanna make it interesting, extend the tubing to the fog light area of the front air dam. Secure it in a fashion that allows air to be forced into it. Now before the flames start, its not a great big improvement, but it does help at certain speeds and or allows more cold air into the area for the filter.
Good luck and you will love how much better the car sounds after removing that heavy worthless box.

Its the intake resonator.

that is why i made a modified short ram. The intake is very complicated, and most of it's components are unnecessary. The purpose of these components is to quiet the car down for everyday driving. Grocery-Getting.

I cut my stock tube back behind all the vaccume lines except the very last one. I plumbed up some fittings that fitted two vaccume hoses back into each other to maintain vaccume, and then hooked one more into the last barb on the intake tube. I then took a spare hose from the installation and fited an oldschool Edelbrock-style chrome breather. This also keeps most blowby gasses away from your intake. On older cars with worn rings this is a must, as with any vehicles that consume oil frequently.


This is all you need from your intake.


Here is the breather setup. The breather costs $3 at Autozone. And yes, that is an MSD Blaster 3 Ignition Coil, suitable for big blocks on my little Sentra... It made a decent improvement.
