What's the difference between cold air and turbo? Like you can't have "cold air" and a turbo on the same car can you? Cold air takes cold air from through the bumper and a turbo just heats up the air and feeds it through, so the turbo just cancells out the point of having a cold air.. Is that true? Feed me some knowledge, I'm a bit new to this stuff so this probobly seems like a stupid question.. So how does that work?
