PPE Intercooler, (2001-05) Duramax LB7/LLY

Even the boost from a huge turbocharger can be choked if the intercooler is inefficient. The factory GM intercooler causes a 2-3 PSI turbo boost pressure drop (wasted energy), but with PPE’s High Flow Performance Intercooler pressure drop is virtually eliminated. Providing 2,142 cu. in. of cooling volume, which is 98% more volume over the stock intercooler (1,083 cu. in.), the PPE’s High Flow Performance Intercooler not only cools more air, it does it faster and more efficiently. In fact, PPE’s intercooler is the largest, most efficient intercooler in the industry, all of which equals more HP and fuel economy for your truck.
