how do i get more power from my 04 audi a6

aftermarket airfilter, followed by ECU upgrade/swap, followed by exhaust. also i would suggest using a higher octane gas. (use premium instead of regular) as the higher octane gas burns faster

When you say aftermarket airfilter u mean cold air intake?

best way is to get it chipped...in my time doing work experience at an audi garage engine chips were the best way to get more power and fuel economy at the same time

ive looked at chips for it but alot of people tell me theirs alot of phony chips out there what one would u recommend?

go get a professional tune done at a shop.

has any body try to use the newer snow system , its a methanal and water injection system , with the higher compression of some of the aidi motors, sounds like might pick up some extra h.p.

first of all, it depends on your budget. Then it depends on your driving ability. The Audi 3.0L V6 is a great platform for "moderate" modifications. Audi dealers have lots of little "tricks" up their sleeves to electronically remap the engines systems and remove any limiters (ie. rpm, speed). You'll pay a lot, but at least the work done will be guaranteed. KONI makes coil over systems for that car that slightly lower it and really firm up the ride. For appearance it's all in the eye of the beholder.
