How does this cone filter work?

I've stared at a photo of a turbo kit but the cone filter doesn't make any sense.

The cold air intake (above the radiator) feeds into the cone filter which in turn feeds into the turbo inlet (back of between engine and firewall) but the cone filter appears to be exposed.
Doesn't this mean that the engine will suck in hot air from the engine bay? :confused:
I thought there would need to be some sort of container around the filter for this set up to work.
 
Yeah you're supposed to put a heatshield in between the filter and the engine. But why put these filters on for any other reason than the sound? They really make no noticeable difference.

EDIT: I see it's also being force-fed air directly from outside via that tube, so perhaps that will offset the amount of hot air sucked in.
 
Think of it this way, although it is a bad install, people normally do the above install without the front intake pulling to the cone, so this is slightly better as there is the addition of the cold air from the front, but the amount of hot air that will be sucked from the engine bay, especially in that position will cancel out most of it.

With this mind set he might as well has kept the standard air box
 
This is jus a lazy install. He is relying on the "RAM" effect from the air intake connected to the cone. He would have done better moving the cone further forward and down, behind or below a headlight for instance.

He could have saved time and money and not even put a cone in at all.

Okay that makes sense but it's a stupid set up.
I'm accustomed to seeing cone filters which filter from the outside to the inside so this cone filter must have both internal and external filter elements?
If not then it appears that the air from the CAI just flows straight through to the engine without being filtered. :wtf:

Nope, it gets filtered from 'inside' as well ;)

Let's look at it this way, why do you prefer cold air on a car? Because cold air is denser and contains more oxygen thus improving combustion.

With a turbo it does not really matter as you are already forcing way more air into the combustion chamber via pressure, more air equals more oxygen.

More pressure also adds more heat. Colder compressed air equals higher density which means more oxygen.

That's why ideally you should have a larger cold air intake, larger turbo & intercooler on forced induction motors in order to lessen heat. Not disagreeing with you.
 
Not to be funny here....but where is the Air mass meter on that car? and if you do use a cone where does the air mass meter go?

The Kia Cerato uses a MAP + wide band O2 sensor setup instead of MAF sensor.
I haven't checked but MAP sensors usually fit onto the intake manifold between the throttle body and the engine.

MAP+IAT sensor is located on the throttle body.
