Just purchased a 2008 A6 3.2 Quattro. I really wanted an '09 with the supercharged motor, but they were a bit out of my price range...and a Certified Pre-Owned 2008 4.2 model was nowhere to be found. The dealership gave me a smokin deal on the '08, so I sacrificed performance for price. However, after a week of driving the car I regret this decision!!

My question is...are there factory items that will significantly increase the HP on a 3.2 motor WITHOUT voiding the factory warranty? If not, does anyone make an aftermarket supercharger for the 3.2 motor?

Any help greatly appreciated.
