PPE Power Intercooler (2001-2005 GM 6.6L Duramax LB7/LLY) - (115040100
Overview
Give your 2001-2005 GM 6.6L Duramax LB7/LLY a major cooling and airflow upgrade with PPE's Performance Intercooler. Designed to deliver cooler, denser charge air, this intercooler improves power, efficiency, and reliability - especially under heavy load or high-heat conditions.
All-Aluminum Bar-and-Plate Construction
Built with a durable all-aluminum bar-and-plate core and welded cast-aluminum end tanks, this intercooler offers far greater strength and heat resistance than the factory unit, which uses crimped plastic end tanks.
32% Larger Core for Better Cooling
The PPE intercooler features a 32% larger core with denser, louvered external fins to maximize heat transfer. The 2-inch thick core is 27% thicker than stock, providing significantly improved cooling efficiency.
Reduced Restriction, Smoother Airflow
The expanded core size and optimized end-tank design reduce airflow restriction, allowing the engine to breathe more freely. This results in improved turbo efficiency, better combustion, and reduced EGTs.
Consistent Performance Under Load
Whether towing, hauling, or daily driving, this intercooler helps maintain stable intake air temperatures and consistent engine performance - even in demanding conditions.
Direct Bolt-On Fit
Designed as a true OEM-style replacement, the PPE intercooler installs easily with no cutting or modifications required.
