What Is an Intercooler?
The intercooler helps turbo and supercharged engines make power reliably. A Cranbourne West specialist explains.
What it is & what it does
An intercooler cools the air after it’s been compressed by the turbo or supercharger (compressing air heats it). Cooler, denser air means more power and safer combustion. It’s essentially a radiator for the intake air.
It sits in the airflow at the front, or is water-cooled on some engines.
Signs of trouble & how we help
Intercooler problems include leaks (lost boost and power), oil collecting inside from a worn turbo, or damage from road debris. A boost leak often traces to the intercooler or its pipes/clamps.
We pressure-test the boost system to find intercooler and pipe leaks that sap power.
