An intercooler on a truck doesn't simply exist to make the intake air "cooler." Its real purpose is to increase charge air density and improve the engine's overall operating conditions.

For a heavy-duty diesel engine, the ideal charge air cooler needs to achieve three things simultaneously:

1. Maximum Heat Transfer:

Remove as much heat as possible from the compressed air.

2. Minimum Pressure Drop:

Avoid making the turbocharger work unnecessarily hard to force air through the CAC.

3. Structural Integrity:

Withstand high boost pressures, vibration, thermal cycling and the harsh operating environment of a heavy-duty truck.

This is why the design of the tubes, fins, headers, tanks, materials and airflow paths is critical, and the reason you should chose a Dura-Lite Evolution for a replacement truck Intercooler.
