Im new to the s4 and just actually bought mine two days ago. I have a 2001.5 b5 s4 and was wondering if the awe intake was the only type of intake you could put on the s4? I know intakes dont add much horse power but i know the stock intake box limits the sound of the engine and turbo spool and I just really want to hear my turbos and DV while im driving. Any suggestions?

 

The best cost/benefit comes from doing the darintake mod (please just search it) which involves cutting holes in your airbox, in combination with a new filter. The AWE s-flo is good, but in all honesy most people dont get very big gains off of any intake, especially when compared to cheaply modding your airbox and getting a new filter.
