Heat is the number one killer of horsepower, fuel economy, and the overall longevity of your Duramax. One of the best methods to reduce temperatures where it matters most is by upgrading the intercooler, and there's no better choice than Banks. This system includes a high flow intercooler, intercooler piping, boots, and clamps for a complete installation.

Superior to stock, everything about the Banks Intercooler system is bigger. It includes mandrel-bent high-flow boost tubes... large, high-efficiency all-aluminum end tanks... a wide-open inlet and outlet... a thicker core area with an improvement in volume. The Banks Intercooler for your LML Duramax dramatically increases the cooling capacity by balancing the richer fuel mixture with greater airflow and cooler, denser air. Denser air has more oxygen, which improves combustion as well as engine efficiency. Result: higher continuous power and more power at any exhaust gas temp (EGT), better fuel economy, and lower EGTs. That's a truckload of benefits! This Banks Intercooler delivers the maximum reduction in boost air temperature with a minimal loss of boost pressure. It doesn't get any cooler than the Banks Intercooler!
