Heat Exchanger for Intercooler - GM 3.0L Duramax 2020-2024

The Pacific Performance Engineering (PPE) Intercooler Coolant Heat Exchanger (MPN: 119010300) is designed for 2020-2026 GM vehicles equipped with the 3.0L Duramax (LM2/LZ0) engine. This high-efficiency heat exchanger features a 20% larger core and more rows of fins compared to the stock unit, increasing the coolant capacity by approximately one quart for improved efficiency and heat stamina. The fully brazed, 18.5 fins-per-inch core and all-aluminum end tanks enhance its heat dissipation capabilities. Optimized two-row coolant tube layout ensures better coolant flow distribution, resulting in a 15% lower pressure drop than the stock unit and a higher coolant flow rate to carry away more heat from the intake air. Installation is straightforward, retaining stock mounting brackets and requiring no grille removal. This unit alone enhances the performance of the stock air-to-liquid intercooler, and when paired with the PPE Air-to-Water Intercooler Kit, it delivers unmatched cooling performance.
