Here are the installation instructions from Carbonio on how to install the Carbonio carbon fiber intake for a 2006-2008 B7 Audi A4 with the 2.0T FSI Engine.

The install is pretty straightforward and should only take 1-2 hours maximum. It is a pretty easy DIY and could be performed by a novice. You don’t really need any special tools – although you definitely want to wait until the engine has cooled down completely before digging around in there!
The end result is a more aggressive sound when accelerating, slightly better airflow, a cooler looking engine bay (carbon fiber is pretty, haha), and a slight woosh noise (almost sounds like a blow off valve) when you switch gears or let off the gas. This is a result of there being no sound deadening in the airbox so you can hear more of the noises and changes in pressure. I’ve actually had people ask what blow off valve I was running because it sounded so nice, and I explained I had no blow off valve and that I was running the stock diverter valve, and it was really just the Carbonio Intake that resulted in the noise.
Before the Carbonio Intake I ran the EvoMS (Evolution Motorsports) Intake for the B7 Audi A4, and it was even louder than this one – too loud, in my opinion. I ended up selling it and switching to the Carbonio Intake and I’m very happy with that decision.
