The Mishimoto 840197701461 17-19 GM 6.6L L5P Duramax Intercooler is a high-performance upgrade for your Duramax diesel engine. This intercooler is designed to replace the factory unit, improving cooling efficiency and reducing charge temperature.

This intercooler features a large, high-density bar-and-plate core, which provides greater surface area for heat exchange. The core is sandwiched between two aluminum end tanks, which are TIG welded for strength and durability. The end tanks are also CNC machined for a precise fit and a polished finish.

This intercooler is designed to provide improved cooling performance, making it ideal for towing, off-roading, or high-performance applications. The larger core size reduces the temperature drop between the intake and discharge air, resulting in denser air entering the engine for improved combustion and increased power output.

The Mishimoto 17-19 GM 6.6L L5P Duramax Intercooler is backed by a limited lifetime warranty, ensuring peace of mind for the life of your vehicle. The intercooler is also EPA and CARB legal, making it a great choice for those who require emissions compliance.
