Upgraded my intake...
I figured I would post this for those people new to the 2.7T (and those who would like a "refresher").
There are many schools of thought on the intake for the 2.7T motor. As the benefits of changing/upgrading the intake are minimal, I still wanted to make sure I am getting the most out of the system now that the turbos are working harder. In all my years of car ownership that I have modded, I have ALWAYS done exhaust and intake together.
I do believe that the Audi engineers got the airbox design correct, to keep the air coming in cool from the outside. I do not like the design of the aftermarket upgrades where the intake cone/filter is exposed inside the engine compartment, no matter how you shield it.
I therefore chose the "S-Flo" system from AWE. these are the components you get:
<img src="http://images15.fotki.com/v232/photos/6/697623/2722369/S_Flo_parts-vi.jpg">
It consists of a mandrel bent tube with a flange and gasket, a silicone coupler, 2 adjustable metal bands, and the special ITG filter.
Installation is very straight forward. This is the stock intake area. You remove the plastic panel (triangle piece) covering the airbox by pulling straight up. The intake tube is seperated by pulling straight up on the fender side, and wiggling free on the front connection point.

Once the cover and intake tube is removed, the 4 electrical connections on top of the airbox are seperated by pressing down on the metal clips and pulling gently. Then disconnect the connector to the MAF (airflow sensor) which is connceted to the tube at the back. The three tubes running across the top are not disconnected, but released from their plastic holders so that they can be moved out of the way.
The top cover has 4 metal clips that hold it to the bottom of the airbox. These are released by hand (except for the one closest to the firewall which is a tight fit, and requires a long flat blade screwdriver). The MAF sensor is released from the air tube at the rear by squeazing the spring clip with a large plier.
Once the top cover is removed (with the MAF sensor attached), this is the factory filter that you will see. It just lifts straight out.

The MAF sensor is seperated from the top cover by releasing two spring clips, and pulling straight out. Then the metal mandrel bent tube is inserted into the cover. The air filter is connected to the metal tube with the silicone coupling hose and clamps.
This is how the filter will look installed into the top cover:

Note that here, I have re-installed the MAF sensor to the top cover. I then found that it was alot easier to install the new setup by removing the bottom part of the airbox, and installing it with the new filter installed as a one piece unit.
The bottom of the airbox comes out very easy, just one hex bolt holds it to the fender, and it sits on two rubber 'bumpers' at the bottom. You just pull straight up to remove.
After the airbox is re-installed, you just reverse the procedure...hook back up the MAF sensor to the rear tube, put the three hoses back in place and reconnect the 5 electrical connections. The nice part about this, is everything still has a nice clean stock look.
I am going to run with this for a week or two, and then re-evaluate whether I want to do the 'Darintake" (which is basically making (5) 1 inch holes to the back of the bottom part of the intake box). The purpose of that would be to increase airflow in the box with cool air not close to the engine.
You can buy the filter seperately, buy a pipe and have it bent at a muffler shop, and the connceting hose to save a few $'s. I just found the AWE setup a nice "one-stop" way of doing this upgrade.
Doing suspension next week

No, your airbox is different....here is a link for yours...

will do! ...I was driving all over around today, checking out the acceleration...
...from different speeds, standstill, rolling start, 40mph punch, 60mph punch.
There was a little hesitation it had on a rolling start before the intake, and now it's smooth and not noticeable.
