Suggestions A4 B8 3.2 Quattro Intake?
 

I recently bought of my first Audi. And I made a deal with the dealer that they will fix me with any air intake I suggest on their expense. Currently I found 3 brands of intakes, which are:
- AWE Tuning
- APR: tried to contact them but they have not yet answered my email.
- Volant: although it is made for A5 3.2, it also gets fitted on the A4.

I am looking for best performance and engine sound results out of this intake, and I am living in GCC where the weather is hot and dusty most of days during a normal year.

I welcome thoughts and ideas
