I was going to buy a ram air hood what one of thiose intakes works best. Please dont flame on me I am very new to cars.
whats a SAI?
And And intake is and intake is an intake. The differance between them in mostly cosmetic. Even a CAI verse a WAI is only a little bit, if any.
sai well i mean short ram air intake what one would be best for a ram air hood? is there an intake that hood directly to the hood?
Neither is better. You need to be going 100+ mph to get any gain from a ram air hood.

The souns is just a culmination of choice filter and piping and the angles.

You need atleast the stock airbox for the ram air hoods. However the rest of the intake tract can be replaced.
Unless you drive 120 on the Autobahn every day, a ram air hood is pointless. But if you want one anyway, keep the stock airbox and replace the funky rubber nitake hose going to the throttlebody with a regular pipe. Most of the ramair hoods I've seen use the airbox as part of the system.

Get what ever is cheapest (within reason). When It comes to cars that push a lot of power, the type of intake matters but our cars produce too little power to notice a big difference between ram air, wai, or cai. I just have a wai cause it's extremely easy to install and maintain.
the best intake ever. a turbocharger.
I was a retard, and now I'm permanently banned.

Old wives tale... Some of the VW guys have logged MAF grams per second with CAI, modded stock airbox, and stock airbox with ram air all the way through 3rd gear, the ram air did give a few more g/sec than either of the others. Is it the same as forced induction? no, but it IS an improvement. Personally if i were the original poster, I'd save my money and go turbo

Ok, more of a new question concerning this . . .
How is a Ram-air pointless unless your going over 100? A WAI is inside the engine bay and pulls in air that comes through. The CAI is usually under the car or in the bumper for the most part and pulls in air that comes through. Ram air is direct and the air is slammed directly into the engine, is it not? There is more restriction with the air getting to the CAI or WAI, so how is a ram-air useless compared to these? I'm kinda lost on that concept . . .
with ram air speed is indifferent. the real advantage to ream air is that your not having to pull in air, the air pressure inside your engine(short ram) bay and fenderwell(cold air) is less than 1 bar (air pressure at sea level).
With a ram air you have less resistance at the source of intake, being located outside the engine bay.
However due to fluid dynamics, it's not going to actually force any air in. If that was true the turbo or super charger market wouldn't be so big because you'd get the same effect the faster you went, as boosting.
A better explanation of ram air would be free breathing, because your removing a good bit of air restriction, However systems like the Weapon R uses, destroys the effect of less restriction by having flex tubing for the ram air kit.
