CoilPacks and performance

[Robert Rossato]

Can't speak to the new style coils, but I recently replaced all the
coils on my '95 S6 (AAN engine) and there was a very noticeable
increase in power.  My coils weren't at the point that they were
misfiring all the time.  I had an occasional misfire on one cylinder
at idle upon a cold start that would go away after a minute or so.
140k miles on the coils when I replaced them.

So they do degrade gradually, in my opinion.
