[size=4] I just completed my first engine mod, on my 2000 s4,the mod being an EVO air intake, works well, and love it, really notice a difference. But now i'm hooked, and i'm looking for the best mod to do now around 300-400 dollars. i'm going to guess a DV upgrade? if you think otherwise feel free to comemt. ive allready went all out on the interior and sound system so if anyone has and questions about that i could probly help ya

 

i say save some more loot and do an exaust system, it would flow nice with ur intake. then do the DV's and chip and ur laughin

 

i was told by an audi mechanic (not at the dealer) that the stock DVs are fine unless they break to run with a chip.

 

Mine are still stock, so far...

 

or save up for a chip

 

yea i saved engough for a chip and driver valves so its good now

 

You can always upgrade to the 710n DV's - they are an OE upgrade for around $40 each. Many guys I know buy a couple 710N's to have on hand if their stock DV's fail. Cheap, but worthwhile investment.

If money is no object, then I vote you invest in Bailey DV's.

 

What do the DV's do?
How difficult are they to install?
