The better part of an argument explained with evidence and science. I have been critical about the black painted intercooler myself but here is everything you need to know
One of the youtube commenters said the following, rather interesting.
"It's not all about power, turbocharged cars are very fuel efficient. A smaller motor can make the power of a big motor, but only when needed. Sitting at idle or low speed with a lower intake temp is a benefit for my fuel economy, as my engine can use even less fuel to maintain enough power to idle. Also, in a drag race, staging (vrooom popopopopopop) a turbo car can see benefits on the line from a cooler intake temp. Just depends, clearly there are advantages and disadvantages to this mod. Decide for yourself what your car might need"

"I think you slightly missed the intentions of my video. Let me clarify: A car doesn't need to cool the intake charge when not moving. There's either a vacuum (and thus no temp increase from compression), or any benefit of radiation will be diminished upon accelerating"
