sweet found the extension for the hose wrapped under my sri thanks again.

Oh btw what does that little black box do?

Chilton's says:
"Intake Control Solenoid Valve"
I'm really not too sure what that could mean; mayhave something to do with the dual stage manifold.

It just opens up around 4000ish rpm and supposedly quiets the intake or something like that or lets more air in I forgot. SOmething along those lines.

This is your stock intake. That little black box is the Vacuum chamber/solenoid assembly.

Basically, there are 2 ducts going into your stock airbox. There is one on top and one on the bottom.

The one on the bottom is called the "high power duct". If you look at the stock one, you will see a big black vacuum diaphragm on the top of it.

This diapragm is attached to a little flap.

When the car is on, engine vacuum sucks on the diaphragm, which pulls the flap closed. This prevents air from travelling through the bottom duct.

The purpose of this is to help keep intake noise down when both ducts aren't needed.

The black box/solenoid store engine vaccum to keep the duct closed, even when the engine isn't producing a vacuum.

Then at 3500RPM and high throttle, the ECU tells the solenoid to open, which releases the vacuum, and causes the flap in the high power duct to open.

That way the engine is quieter at low speeds, and allows the engine to breathe enough at high rpm.
