Charge Air Cooler for International 9900 (1999-2007)

Heavy-Duty Aluminum Charge Air Cooler for 1999-2007 International 9900 (9000 Series Conventional)

What it Does: The Charge Air Cooler cools compressed intake air discharged from the turbocharger on the 1999-2007 International 9900 to lower intake manifold temperatures, restore boost density, and prevent power loss.

The Stock International 9900 Thermal Fatigue and Boost Leakage

Factory charge air coolers on high-mileage Class 8 haulers undergo constant thermal cycling and boost pressures exceeding 30 PSI. Over continuous operational hours, the original brazed core tubes develop micro-fractures, while end-tank seams separate under mechanical vibration. Internal oil mist buildup combined with core leakage creates substantial pressure drops across the induction system. Even minor boost leaks cause the turbocharger to overspin, resulting in spiked exhaust gas temperatures (EGTs), heavy black exhaust smoke, degraded fuel mileage, and noticeable loss of low-end hauling torque under heavy load.

The Engineering Solution

Engineered as a robust direct-replacement upgrade, this heavy-duty aluminum cross-flow charge air cooler restores factory intake pressure retention and thermal transfer rates. Featuring high-tensile, furnace-brazed aluminum core construction, it withstands aggressive thermal expansion without developing stress cracks. The core geometry matches original equipment dimensions with factory-located inlet and outlet ports, ensuring standard silicone boots and high-torque T-bolt clamps mate seamlessly. By providing dense, low-temperature air to the manifold, this unit optimizes fuel burn efficiency and safeguards against elevated turbine temperatures on steep grades.
