In another question I confirmed what a hood scoop was. I was also wondering what this structure was since it was differently shaped than a hood scoop. I heard it was a "turbocharger" or something like that and that it helped to shove air into the engine and speed the car up. What is it? What's its purpose and do they still make them? Also what cars feature it? I saw it on a Charger and I think other new ones but I am not sure since a lot of turbochargers don't look like this?
