Improved Cooling Performance for 3.0L Duramax

The PPE Intercooler Coolant Heat Exchanger is a must-have upgrade for anyone looking to maximize cooling performance on their 2020-2024 GM 3.0L Duramax. Whether you tow heavy loads, drive in extreme temperatures, or simply want to get the most power and efficiency from your truck, this high-efficiency heat exchanger helps keep intake air temperatures in check. A cooler intercooler means denser air, better combustion, and improved overall performance, ensuring your Duramax runs stronger for longer. One of the biggest limitations of the factory intercooler system is its reliance on a front-mounted coolant heat exchanger. When this stock unit becomes heat-soaked—especially under prolonged high-load conditions like towing or climbing steep grades—it loses its ability to effectively cool the intake air. The result? Reduced power, increased strain on your engine, and overall performance loss. The PPE Heat Exchanger solves this issue with a 20% larger core, allowing it to absorb and dissipate more heat while adding one full quart of extra coolant capacity to the system.

Built for Durability

Built for maximum durability and efficiency, this unit features heavy-duty all-aluminum end tanks and an 18.5 fins-per-inch core for superior heat dissipation. Its two-row coolant tube layout is optimized for improved flow, resulting in a 15% lower pressure drop compared to stock, which means coolant moves faster and removes heat more effectively. The result? Lower intake air temperatures, improved throttle response, and better sustained performance under heavy loads. Installation is straightforward with its direct bolt-on design that requires no grille removal. It mounts using the stock brackets, ensuring a seamless factory-like fit without any unnecessary modifications.
