Turbo Intercoolers And Charge Air Coolers
An intercooler cools compressed intake air between the turbocharger or supercharger and the engine. Cooling the charge increases its density, helping the engine receive more air for a given volume.
A-Premium offers charge air coolers for selected applications. Their position, core shape, mounting and air connections must match the vehicle's induction system.
Choosing An Intercooler Replacement
Some vehicles use a side-specific cooler, while others have a different layout. Compare the inlet and outlet connections and mounting points as well as core dimensions; a similar-sized core is not necessarily a direct match.
A low-boost or hissing concern can come from a damaged cooler, hose or connection. Inspect the charge-air path and diagnose the source before replacing parts.
Frequently Asked Questions (FAQ)
Is an intercooler the same as an engine radiator?
Both transfer heat, but they serve different circuits. An intercooler cools compressed intake air, while the engine radiator removes heat from engine coolant.
Do all intercoolers use outside air for cooling?
Cooling layouts differ. An air-to-air cooler transfers heat to outside air; an air-to-liquid system uses a coolant circuit and heat exchanger. Match the vehicle's original design.
Does oil inside a charge air cooler always mean the turbo has failed?
Oil residue is not enough to identify a failed turbocharger. A manufacturer bulletin for certain engines describes some residue as normal and calls for further inspection when the amount is excessive.
Will a larger intercooler automatically increase horsepower?
The result depends on the complete engine and induction setup, not core size alone. A replacement must fit the vehicle's connections and cooling system; any performance change varies with the application.
Can a leaking charge hose cause the same symptom as a cooler leak?
A split hose or loose clamp can allow pressurized air to escape and reduce performance. The hoses and connections should be inspected along with the intercooler core.
