2020-2023 GM 3.0L Duramax LM2 LZO Air-To-Water Intercooler Kit Black PPE Diesel

The PPE high-performance water-to-air Intercooler adds both style and performance to your 3.0L LM2, LZO Duramax. It 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 also helps reduce exhaust gas temperature (EGTs) and increase fuel efficiency. It significantly improves airflow and lowers pressure drop due to flow-optimized, cast aluminum end tanks and a larger, less restrictive core structure. The PPE intercooler is 77% less restrictive than the stock GM intercooler. 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. Real-world testing showed IAT reduced by as much as 30 degrees compared to the factory cooler.
