2020-2023 GM 3.0L Duramax LM2, LZ0 Air-To-Water Intercooler Kit

The PPE high-performance water-to-air Intercooler adds both style and performance to your 3.0L Duramax. The PPE intercooler has increased cooling efficiency due to its all-aluminum Bar And Plate-style construction, superior fin layout, and 2.4 times larger core. Cooler and denser charge air can also help reduce exhaust gas temperature (EGTs) and increase fuel efficiency. It also significantly improves the airflow and lowers the pressure drop by up to 17%, which results from the flow-optimized, cast aluminum end tanks and a less restrictive core structure. The kit is complete with a die-cast support bracket, a billet aluminum turbo adapter that replaces the turbo resonator, and PPE Performance Silicone Couplers and Coolant Hoses.
