Well I just tried just an intake on a short pipe. You were right willwren, the sound is barely perceptible. I did not feel a thing in power increase either. I think I will need to take out the stock airbox, and get a longer pipe to the tb. And remove that stock tube you were talking about.
Drill a hole as close to the filter as you can in a long pipe. Yes, the longer the better. It gives the air a chance to settle down and straighten out. Our cars prefer laminar flow, which is why GM put the restrictive MAF screen in. To straighten it out before it gets a reading off the sensor. That long pipe is invaluable. You won't lose performance with a short ram, but you have alot more to gain going long.
As far as the IAT is concerned, just drill that hole and use a rubber grommet. If you go to the 'return of adtr' post in the vendor forum, you'll find a pic of ADTR#2 in my engine bay. You'll see where my IAT is, and get a better idea of how to mount your pipe.

Well, for now I have decided to take out the front airbox, and put a long pipe in as per your suggestion. I will keep the stock air delivery tube for now, I will get a friend to help me take that off, and place the MAF and IAT sensor inside a longer a little later. BTW, is pvc piping ok, or should i really get steel or aluminum piping? I have metalic tape to wrap the pvc in, so that should reflect a bit of heat.
Leave your Maf sensor in the TB. Just remove the screen and set it aside for safekeeping. Move the IAT to the tube. PVC or ABS isn't the BEST idea, but it works. Every joint in the fittings disrupts the airflow. You need smooth wall, LONG ram to be able to remove the Maf screen. Aluminum would be best, as it disipates heat better than steel, but either will work. You want a mandrel bend, as well.
I did not put a CAI on my car at all and I get a great sound from it even when it is warmed up. I gutted the airbox and installed a K&N air filter and also removed the MAF screen, but Ileft the stock intake tubing. The increase in power was not huge but noticeable, and I got a great sound along with it.

Hmm, to take out the front airbox, I cannot seem to get a screw out at the bottom. It is at the bottom and the last screw holding it in place. I cannot get at it because of a plastic piece over it, the only way seems to be from the side.
