What is a key advantage of using a turbocharger?

A turbocharger is a device that forces more air into the engine's combustion chamber, which allows for more fuel to be burned and ultimately increases the engine's power output. One of the significant advantages of using a turbocharger is its ability to enhance performance at higher altitudes. As altitude increases, air density decreases, which results in less oxygen available for combustion. A turbocharger compensates for this loss by compressing the thinner air entering the engine, thus maintaining power output levels that would typically decline due to altitude effects.

This capability is particularly valuable for aircraft and vehicles operating in mountainous regions or at high elevations, where naturally aspirated engines would struggle to perform efficiently. The other options, while potentially beneficial in their own right, do not encompass the primary advantage offered by turbochargers in this context.
