[BiturboS4] newbie questions

[Bill Coleman]

Hi all,

Got my S4 last a couple weeks ago, and just found
this list today.

The car is a 2000 silver/silver 6sp with 59k miles on it.
It's stock (so far) except for a Remus (sp?) exhaust. I
have a few pictures of it at:

Being new to the list, it's my responsiblity to ask a
couple dumb questions, right?  So here  they are:

1) I took the car in for service as soon as I bought
it.  The dealer told me the spark plugs needed to be
replaced.  The ones they took out are marked NGK
PFR6Q which I thought were supposed to be quad
electrode - but I only see one - what am I missing?
BTW the car does seem to run better with the new
plugs installed.

2) AM radio reception sucks - lots of engine noise
bleeding through especially when I first start the
car.  I have an A4 (2001 Avant 1.8tq) that doesn't
seem to have the problem.  Any ideas?

Bill
