An intercooler is another name for a heat exchanger; it is used to cool air to the engine that has been compressed by either a super charger or turbo charger.
The intercooler is positioned in the path of incoming air that flows from the charger/turbo to the engine and improves the power and performance of the vehicle by increasing the intake air density.
There are two types of intercooler; an air to air or an air to liquid.
How to notice Intercooler failure:
- There will be a lack of power when you accelerate
- The fuel economy of the vehicle will decrease
- Black smoke will be seen coming from the exhaust system
