Answer 1

Explanation:

Intercooler:

The intercooler is an additional component that looks like a radiator, except that air passes through the inside as well as the outside of the intercooler.
The intake air passes through sealed passageways inside the cooler, while cooler air from outside is blown across the fins by the engine cooling fan.
The intercooler is used in a vehicle with a turbocharger.

Additional InformationTurbocharger:

A turbocharger is mounted on the engine.
It increases the amount of air delivered to the engine cylinder, thereby more fuel can be burnt which increases engine power.
Whenever the density of air is less than the density at atmospheric pressure, especially at higher altitudes, the turbocharger helps the engine to get sufficient air.
An engine may have one or more turbochargers.

Radiator:

The purpose of a radiator in the cooling system is to cool hot water coming out of the engine.
It has a large cooling surface area to allow enough air to pass through it.
Water circulated through it is cooled by the passing air.
