because its short
a cold air intake is long and usually consists of two pipes joined by a coupler and they go down into your bumper
on a short ram like this one, the filter is still inside the engine bay unlike the cold air, where it is inside your bumper

what do you mean 'ram air' and 'make something for it'?
you just remove your stock intake assembly and install the short ram
sorry if i didnt understand correctly

Ram air would be if there was a scoop somewhere on the car with the filter behind it, theoretically forcing air into the intake at higher than atmospheric pressure and at speed. However, I had to use the word 'theoretical' as a true ram air effect would be seen at higher speeds than a civic's gearbox allows.

Even if you take the pressure out of the equation and focus on the speed the air will be flowing, you have to have a straight shot into the cylinders for it to be effective; with the turns in the air ducting as well as the 90 turn the air has to make in the intake manifold, any and all gains would be lost by the time the air saw the combustion chamber.

No, I'm saying ram air really only works in theory. A short ram intake will be able to flow a larger volume of air than the stock intake and a cold-air intake will be able to flow as much air as the short ram intake, only pulling it from a colder location. Personally, I'd recommend a cold-air intake for the fact that it gains a little power over the stock intake (maybe 1-2whp, you won't be able to feel it, but it's still a gain) and it will keep that power gain even when the engine bay is heat-soaked (say, after 10 minutes of driving).
