Integral to the new 4.0-liter Twin Turbo engine's power output is not only the turbochargers but the charge air (compressed air) cooling system. A system to cool the charge air is required because when the turbochargers compress air, it heats up. For optimum performance, this air needs to be cooled again. Cooler air going into the engine means much denser oxygenation and improved knock resistance, two key factors when seeking to maintain or improve power.

This cooling system consists of two charge air coolers which cool the charge air, a water circuit that flows through a pump, into the charge air coolers, and into a heat exchanger, which then cools the water that has been used by the charge air coolers to cool the compressed air.

As boost pressure is increased, more heat is introduced into the charge air cooling system. The stock charge air cooling system works very well for stock boost levels; however, once boost levels are raised, it can struggle to keep charge air temperatures consistently cool.

The CSF Performance all-aluminum Heat Exchanger (Charge Cooler Water Radiator) improves the cooling power of the stock heat exchanger, which cools the water that cools the charge air. With a more robust heat exchanger, it can more effectively remove heat from the hot water to help keep charge air temperatures cooler and improve resistance to heat soak.
