What do you call the air induction system that uses a hood scoop?

Question

I am looking for what you call the system that uses a hood scoop to push air into the engine. Also looking where I can get it for a '06 Focus ZX4 ST

Answer 1

Cold air induction?

Answer 2

Hi If you're after looks only, then place it wherever it looks best to you (but you might want to get a second or third opinion!). Performance wise, the hot air is exhausted out the back of the engine compartment by the fan and the motion of the vehicle so other cooling is usually not needed (except for disk brakes which is another story). The object of a hood scoop then is to direct cooler, more oxygen rich air into the air intake of the engine to yield more horsepower when the car is moving. For performance, it should be directly connected to the air intake (usually with some tyoe of foam gasket so that the hood can be easily opened. Many modern cars, however, utilize an air intake in the air dam on one side or the other of the radiator, creating a similar effect as a hood scoop. Since manufacturers utilize computers now to aid the design of the airflow over the vehicle (and into the engine air intake) it is unlikely that you could improve performance much, if at all, on a newer vehicle (90's and up). So that takes it all back to looks! Hope I have been of some help with your decision!

Answer 3

Its a NACA duct.

800 - 262 - 8099
NACA Ducts


NACA ducts are useful when air needs to be drawn into an area which isn't exposed to the direct air flow the scoop has access to. Quite often you will see NACA ducts along the sides of a car. The NACA duct takes advantage of the Boundary layer, a layer of slow moving air that "clings" to the bodywork of the car, especially where the bodywork flattens, or does not accelerate or decelerate the air flow. Areas like the roof and side body panels are good examples. The longer the roof or body panels, the thicker the layer becomes (a source of drag that grows as the layer thickens too).


Anyway, the NACA duct scavenges this slower moving area by means of a specially shaped intake. The intake shape, shown above, drops in toward the inside of the bodywork, and this draws the slow moving air into the opening at the end of the NACA duct. Vortexes are also generated by the "walls" of the duct shape, aiding in the scavenging. The shape and depth change of the duct are critical for proper operation.

Answer 4

Ram-air,shaker,cowl induction,grabber scoop some names used by Pontiac,Chevy,and Ford.
It may be cheaper to plumb in a cold air with a K&N filter somewhere in front of your radiator area!
The key in your case may not be for a huge volume of air but for cold air in general to make power.

Answer 5

I believe it's called ram-air, many muscle cars used it. You may need a custom install to have a true ram air on the Focus.

Answer 6

mustang mach 1 uses a hood like you are talking about it is called ram air ws6 trans am also uses ram air

Answer 7
