As it seems to be the most popular topic asked in the B5 S4/RS4 forum, this BOV/DV/BPV thread will be for any and all information aimed to help those who are curious about which BOV or DV to run on their 2000-2002 S4.

Please post any informational thread that contains no flaming -- only good, car related information -- that may help others learn why our car reacts differently to various set-ups.

Also, I would greatly appreciate links to the cheapest / most reliable places to purchase aftermarket DV's.

Thanks!
