Hey guys, Just got a new 2006 S4. I Absolutely Love this car!! I'm new to the game however. I was wondering if I could pick your minds for some help. I am interested in modifying this vehicle to get what I can out of it. I have a budget of about $4000 to add to it right now. What would you guys add with this kind of budget? One question that I have is regarding the Hyper Flow Air induction kit. I have heard some conflicting reports about the utility of this modification. Stratmosphere states that you can expect gains of around 10 HP to the wheels, whereas, Motodyne does Not recommend it if you only have a single fuel rail system. I was wondering what you guys think. I'm also looking to chip it out. Which chip do you guys recommend (APR , GIAC, etc..). Thanks guys!!!!!!

 

bang for the buck you will get the most out of a full milltek exhaust set up
they claim 40lbs trq and 30 horses increase...
I think all chips are worthless so far... jumping up at best~~ 10 horse...and that at a certain peak of acceleration--very well perhaps having diminished performance earlier in the band..most are detrimental-- wheres that link
intake sounds good but I dont think it does much

MOtodyne said single fuel rail? I thought stock there was 2 rails, but do they mean fuel rail with no return? Whatevr I am not a tech nor know what that means
some one tell me

Looks wise if you get some coilovers and lower it, it will look beautiful, stock you ride the same height as an a4
I recc bilsteins pss9 it actually rides more comfortable than stock

let us wait for these reported and rumored less pricey superchargers

 

I think this is what you were looking for B6 S4 Dyno Shootout
