IS THERE A HUGE AUDI FAN,WHO KNOWS WHERE TO GET HIGH PERFORMACE STUFF FOR MY 2004 A6 3.0 ????????

 

The only real performance mod for the3.0 is a PES supercharger, other than that you can do exhaust but it won't get you much power (just sound and looks). You could also do suspension, rims, and brakes, which won't make it faster but it will be more fun to drive.

 

This place seems to have good stuff for audi's. Prices are pretty reasonable (for Audi!) too.

I have an '02 3.0 A6. I upgraded to H-sport sway bars at PURE Motorsport (www.purems.com). There's a couple of excellent write ups on here and audiworld on how to install them too! They make a huge difference in overall handling and steering. Also put 18" rims on for the summer months.
