Spark Plug Question

["Engstrom, Gerald A (APL)" <GAEngstrom@taylorcorp.com>]

I'm sorry to ask this question, as its already a moot issue, but I'm
having trouble determining what is the "best" plug to use in a turbo.  I
have a 94 S4 20v.  Ive seen a lot of negative press on the list for the
"Cheap" Bosch Platinum.  I did not know there was an expensive platinum,
how much is it?.  I have seen a recent post stating the Bosch Silver is
more reliable, so I'm a little confused as to what has been the best
experience.  I would really like to hear some of your experiences and
look forward to your responces.  Feel free to e-mail me directly and
Thank you.
