I suspect that *most* of these cars are driven usually to shows, and
special events. I don't see many driving to work and back every day. In
the early days, the idea (besides looking cool), was to get the least
amount of restriction and the most air flow. Which is NO air filter (but
some kind of air entry smoothing device), or velocity stacks or ram tubes
which tune the incoming air at narrow engine RPM ranges for maximum
velocity. With race only cars, you would be rebuilding the engine after a
couple of races anyway (if you were lucky). Little regard to engine wear.
Things are a little different for our daily driven vehicles :-}.
