Custom Intercooler When air is compressed by a supercharger or turbo, the process of compression increases its temperature by a significant amount. This is where an intercooler comes in. Intercoolers are placed in front of the radiator so they have access to ambient airflow. The ambient temperature air cools down the hot compressed air as it flows through the intercooler. As cooler air is denser, this enables the engine to make more power and also protects against detonation (knock). Most…
