New to Audi's: Basic Questions

[tlazay@ultranet.com]

Sorry to bog down the archives with such simple questions. Unfortunately, I
can't have hundreds of emails coming in every day and the lag time for me on
the web archive site makes it too expensive and time consuming to read every
article.

Anyway, I am new to Audi and currently have a silver 97 A4 quattro coming in
a few weeks from now. After browsing the archives, I can't seem to find the
answers to several questions I have about this model. Any feedback would be
greatly appreciated.

1) Electronic Differential Lock: What is this? How does it help? When does
it engage?

2) CD Changer: Do you really have to pay the dealer $600 to install a
changer that one could install by themselves for $300? Could one install an
"off the shelf" changer from Crutchfield or any other similar outfit?

3) Tires/Snow tires: Do you recommend snow tires for this car? If I were to
put high performance tires on, what make and size would give the best
performance (dry weather).

4) Performance Upgrades: Are there any chips or air filters which would
increase the 172 hp? I must admit that although I love the car, it was a bit
sluggish in the 20-60 mph acceleration range compared to my present car.


Thank you very much!
