I used the utmost care not to touch the IAT but I'm not sure if my friend did when he was handling it, which is one of the reasons I decided to go out and buy a new one. But the new one isn't working either.
I'm really hoping that the new one got messed up in the over night shipping, also the sales guy at the store I bought it from handled it pretty carelessly. I'm going to try and get the MAF. Off of my buddies sti and see if it works. *fingers crossed*
Sorry if the spelling was crap, I sent this on my phone.
Well, I took it to Subaru and I paid them $100 to diagnose my car, and they told me what I was already suspecting, the MAF is faulty. I really wish the auto part store sent me a functioning MAF to begin with. :/
Thanks for all of the suggestions and help.
I'm short on time right now, but I will post pics and the solution I found later today.
I feel that this solution and the problems presented here could be extreamly helpful to others. I learned a very expensive lesson today, and I want to do everything I can to help others learn it for free.
Alright, I'm very sorry for the extreme late reply, but I'm a full time student with a full time job living on my own so we know how that goes...
Anyways, this is the correct way to install the piping...
It's quite obvious that the piping is supposed to fit this way. It fits perfectly and when installed backwards it's crooked.
I was reading online about MAF sensors and I came across a thread stating that the MAF needs at least 3 inches of straight piping in order to function properly. After thinking over this I noticed it did not indeed have 3 inches of piping.
So that's when I installed the piping like this...
When it's installed this way, it's quite obvious that it's not supposed to be oriented like this. Whoever made the cold-air kit installed it like this to begin with and placed the MAF hole according to this orientation and this is what caused me so much trouble.
Long story short, make sure you have 3 inches of straight piping before taking your car to the dealership to get inspected...
Also on a side note the dealership just told me I needed a new MAF sensor and did not look at the piping at all.
Crazy, but sounds like that's the fix. I'm glad I'm rubbing the stock setup with a K&N filter. :-D
Ha yeah, I have also heard that plastic is a better insulator than metal any ways, and I've noticed that the engine bay on this car gets a lot hotter than other cars.
In the picture on top, the MAF is installed backwards.

After a little while I felt a little better, but very little. I needed a drink, I needed a lot of life insurance, I needed a vacation, I needed a home in the country. What I had was a coat, a hat and a gun. I put them on and went out of the room. Fairwell, My Lovely

Time to rescale your MAF or put the stock one back on.

Not on this piping it wont. After mycologist posted about the orientation I tried to install it the other way. It only fits one way.
