What is the sensor on the air box of my V6 firebird? It has 2 wires coming from it (black and tan). Its right before the MAF. I am just trying to get an understanding so I can replace the whole intake with a straight pipe. Also, how do I know if I need a new sensor and where can I get one? Anything would be appreciated. Thanks guys!

 

I believe it is the IAT sensor (inlet air temp.)

 

Without a scantool, it would be hard. You could have a thermometer in the inlet air and read the scantool to see how many degrees the air is. If you need a new one, you can get it from GM

 

Thanks.

 

Just curious, what does the ECM do when the temperature changes up or down?

 

Adjusts the fuel mixture if it's in open loop....if it's in closed loop, not much.

I am thinking about using hose like that. Opinions on that?
(I can work with tools, I just don't know alot about engines so I check here)

 

Now thats different, Ive never seen that one before. Why dont you just glue a bunch of toilet paper rolls together?

 

What kind of hose is that silvery thing made of? Would it collapse under the vacuum?

 

The guy seems to have had good results. I was skeptical of that too.

 

Its only getting ported vacuum, so it shouldnt be over 3 in.

 

He is using a dryer hose of 4 in for the TB intake?

 

Thats what it looks like.

 

I wouldn't. But that is just me.

 

Maybe there is some re-enforced dryer piping there? I know the fire trucks around here have stuff that looks like that but is rigid plastic rather than just flimsy dryer pipe.
