I’ve Never seen something like this. It’s a radiator on the air intake of the engine. What purpose does it serve? The colder air is more dense, so it combusts faster? What is the ideal temperature of the air going through the intake? I can see you could go overkill and possible have the air go through a chiller. I’ve just never heard of a radiator on the intake before, not sure of it’s purpose. You can add in this radiator on any car? How much measurable benefit would I see (if any)?
Looks odd to me, faster warm up? Where are the connetions to the real radiator?
It’s called an intercooler, It’s to cool the compressed air from the Turbo.
Air heats up when it gets compressed, that’s why it goes through an intercooler, to cool it back down.

no connections to the real radiator, except in the case that one is mounted in front of the other, then the same air will pass over the fins of both (not internally of the intercooler.)
As @It_s_Me said, it’s an intercooler, and a pretty standard component on turbocharged and supercharged systems.
These are becoming pretty standard components, since most new cars nowadays use some combination of turbocharging and supercharging to achieve better performance and fuel efficiency (by achieving the same amount of power with a smaller/more efficient engine). My 2018 Volvo XC60, for instance, has both a turbocharger and a supercharger (and an intercooler) as standard equipment.
You could not tell it was turbo intercooler?
Apparently not. I’m sure half the folks out there would have no idea what that was.
do you really think they would have asked if they knew???

Then I’m guessing you haven’t seen many engines in general then
It’s an intercooler, most turbo/supercharged engines have them.
cools the incoming compressed air so that it’s cooler.
There have been experiments over the years that use the car’s HVAC system to cool the air further, some vehicles (newer BMW M cars for example) has a system that sprays the intercooler with water to get an evaporation cooling effect, which allows for more aggressive ECU tuning.
They are only practical in vehicles with forced induction as the air is being effectively heated by the turbo/supercharger. The air gets hotter due to being compressed. On N/A engines, this doesn’t happen.
It was a test
WHAT 
Not on any turbos I know of.
even on Comprex supercharger, where intake and exhaust are seemingly connected… they are NOT mixing
Sorry, yeah, I misspoke. I was pretty spaced out this morning, haha.
rednecks call them “racing radiators”
