I recently was introduced to the glory that is Audi, and I immediately went on a quest to find my very own. For 3 weeks now I have been the owner of a 2000 Audi A6 Quattro, 4.2L. I have been trying to learn as much as possible about this vehicle, but I find that information is scarce.

I am a Mechanical Engineer, recently graduated, and I really enjoy doing design work. I spend a lot more time than I like to admit doing CFD and Fluid Mechanics... good for things like intake and exhaust.

I'm looking for any advice about what I can do to make my Audi even better than it is. I'm not looking to go crazy with the horsepower, I'm just looking for efficient ways of improving performance all around.

Thanks in advance for all your feedback!
