This would be why your fuel economy improves in winter. Not.
There are a few reasons why cars get worse mileage in the winter, one being winter fuel formulations having less energy content, another being that colder/denser air creates more aerodynamic drag.

Another secondary effect is that since colder air *does* give more power, then at a given cruise speed, you'll have a smaller throttle opening to make the same power. This gives greater losses as the engine has to do a tiny bit more work to draw the air past the smaller throttle opening.

Believe it or not, there is a HOT air intake mod for mid-90s Honda VX cars that improves fuel efficiency for this reason (wider throttle opening required for a given speed/power setting)!


That said, I would guess that most CAI mods for this car won't necessarily improve performance much, if at all. That has been the case with a lot of S2000 intake mods...
