It depends on the car. My Mustang gets air from the fender which is
not very efficient. So a ram air that I made out of $10 worth of a
clothes dryer ducting material helped throttle response even at 20mph
or so. 

Most of the newer cars already have a similar setup of ramming air
through ducting into the throttle body.

Although, there's alot more bugs and gravel in my air filter, so
that's kind of scarry, and puddles of water can be bad too, so I took
it off.
