Upgrading the intercooler on your 2020-2024 GM Duramax 6.6L L5P is a great way to improve engine performance and efficiency, especially under demanding conditions such as towing or off-roading. A high-quality aftermarket intercooler ensures cooler, denser air reaches your engine, resulting in better power, efficiency, and throttle response. Our selection of GM 2500HD/3500HD intercoolers offers superior cooling efficiency and durability, helping to reduce intake air temperatures and prevent heat soak during extreme driving scenarios. Pair your new intercooler with some Intercooler Pipes & Accessories for even better airflow and more performance gains. GM Duramax Fitments: 2020, 2021, 2022, 2023 and 2024 GM 6.6L Duramax.
