Unlock the full potential of your 3.0L Duramax with the HD Performance Air-to-Water Intercooler Upgrade Kit. Designed specifically for GM's LM2 and LZ0 diesel platforms, this premium intercooler system delivers significantly improved charge-air cooling, reduced intake air temperatures, lower exhaust gas temperatures, and increased airflow efficiency under demanding driving conditions.
Whether you're towing heavy loads, climbing steep grades, daily driving, or running performance tuning, maintaining cooler charge air is critical to maximizing horsepower, torque, fuel efficiency, and engine reliability. The HD Performance intercooler features a high-capacity all-aluminum core engineered to outperform the restrictive factory intercooler while providing consistent performance in extreme temperatures and high-load situations.
The upgraded intercooler design increases cooling surface area and airflow capacity, helping your turbocharger operate more efficiently while reducing heat soak commonly experienced during towing and repeated acceleration. Cooler, denser air allows the engine to maintain optimal combustion efficiency and power output when you need it most.
Performance intercoolers utilizing larger bar-and-plate core construction have demonstrated substantial reductions in intake air temperatures while improving airflow and reducing restriction compared to factory units. Similar designs have shown up to 30°F lower intake temperatures, significantly larger core volume, and reduced pressure drop for improved engine breathing.
