Carbonio Intake on a B7 Audi A4

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.

  1. The thing I love most about installing an intake system is that it is just about the easiest upgrade you can make. Not to mention fairly inexpensive for the results. Nice article, and the Carbonio Intakes are very nice.

  2. Hey Nick, I know that the Carbonio Intake can improve some audio with the engine but I was wondering what performance enhancements does it give?

  3. I believe it does add some horsepower but it’s most effective when matched with a tune such as the APR Stage 2 tune that is designed to accommodate for a greater airflow through the intake. I don’t have before & after dynos with only the intake unfortunately.

  4. I installed my intake and one of the screws used to hold on the carbon fiber top on doesnt line up with the hole (The second hole). I dont think it will cause a problem, what do you think?

  5. As long as there isn’t any major gaps in holding the air in the intake box you should be fine. The idea is to force the air into the air filter so any major leaks outside of the intake box should be avoided.

  6. Hey Nick thanks to your article I’m planning on ordering a Carbonio Intake. I was also wondering where you got your battery cover from.

  7. I think I just got it from my dealership or – it’s an OEM part, so anywhere that sells OEM parts can sell you one…

  8. Hey Nick I had a quick question about the intake. Where did you purchase you yours from? Did you have a website you went to? Also where did you get your turbo inlet pipe from?

    Your diys have been such a huge help!


  9. Happy to help! I bought my intake used but you should be able to buy it from any authorized APR dealer – I’d do a Google search and see what comes up in terms of price + shipping and go with that…

  10. Nick- Did you ever end up upgrading your stock DV to the newer B8 one such as The 710n or 710d, on an earlier conversation we had you had told me the stock ones were prone to going bad.

  11. I know this is an old note chain, but wondering if anybody can tell me what I need to do to maintain this system? Do I need to replace the filter after time or miles? Do I need to wash or oil the filter?
