I have seen many people talk about getting cold air into the engine is much better than more but I want to know why people would believe this. To me cold air doesn't matter for anything if you aren't getting enough air into the engine in the first place.
Basicly I just want to know what you guys think.

It is interesting to note that in the latest Car Craft they dynoed a 520 hp engine with no aircleaner, a very tiny filter, a little bigger one, et., etc., on up to a very large one. The size made no difference in the amount of hp produced. This is significant because it flies in the face of 50 years of hot rod philosophy which stated that you need the largest filter possible in order to develop power. Thus the answer is cold air

The reason you want cold air is because it mates with the gas and creates a denser fuel mixture. that's what i've always been told.

Yes, it is because cold air is denser allowing more fuel to be burned at one time, thus creating additional hp.Originally posted by bradkeith

That is why the 305 HO dual snorkle aircleaner is so covetted.

Cold air works at all speeds. More air (sometimes called ramair) works only at higher speed.
Homemade cold air systems or SLP cold air gives you cold air and more air by virtue of larger air filters (over stock).

Kinda funny question, cause cold air is more air! I know that's not how you mean it though. IMHO, for something no less restrictive than stock, I'd take the cold air. Haven't seen any scientific research, tho.

Did they have some kind of fan in front? On a dyno the car isn't moving so there is no airflow. Correct?Originally posted by Sitting Bull

Nope, just the engine and open element filters. Originally posted by Mark A Shields

A dual snorkle outfit like the 305 HO has been proven to knock an additional .25 seconds from your ET. It's the best of both worlds: cold air from in front of the car, and ram air at speed

I'd go with the COLD air.
I know when I go to the track, all the air intake mods I've done don't compare to the extra power I get from a good icedown of the intake.

How about more cold air? 
As in, a ram air/cold air setup. You just need to lead ducting from below the car so it meets the air filter.
