What kind of parts are you looking for?
since the B6 S4 is pretty new, there arnt any hardcore mods available for it yet. I've heard some talk of a supercharger in the works, but nothing definate. For now, you'll have to live with chipping, exaust and intake. Rims and brakes are also an option. check out AmD Technik, they've got some sick stuff.
Their Stage 3 upgrade includes chip remaping and catback exaust... and is suposidly good for 415bhp. It'll set you back $4000 tho.
