01-05 GM LB7/LLY Duramax BD Xtruded Cool-It Intercooler


Designed through testing at 130+ psi turbo boost pressure and 500-degree F turbo outlet temperatures, our extra thick cast end tanks with support struts have integrity and long life without ballooning and cracking. Curved cross sectional extruded tubes allow additional air flow to the radiator versus square bar and plate designs giving 57% more cooling surface, more power and better fuel economy. Xtruded core and cast end tanks withstand over 130psi of boost for your street or race truck. The tubes have a 0.025" wall thickness and designed enhanced inner fins that add to performance and already strong support structure resulting in a 95% heat conductivity transfer. No cracking or separation occurred when tested at over 400 psi. Colder intake air temperature results in lower EGT's. BD's free flowing Charge Air Cooler (CAC) design with streamlined external air passages improves engine cooling while offering less fan noise and less blade resistance, plus, improving engine power and efficiency of the radiator and air conditioning heat exchangers. This is one of the best intercoolers out there for the 01-05 GM 6.6L Duramax diesel equipped trucks.
