The Mishimoto 2017-2019 GM L5P Duramax Intercooler Kit is engineered to optimize the performance and reliability of your Chevrolet or GMC heavy-duty truck. Designed specifically for the 6.6L Duramax engine, this kit features a robust 68mm-thick bar-and-plate intercooler core with cast-aluminum end tanks for superior heat dissipation and durability. The larger core and end tanks reduce restriction by over 64 percent compared to stock, significantly improving airflow and cooling efficiency, which is crucial for maintaining optimal engine temperatures during demanding hauling or towing tasks. This upgrade ensures your truck can handle high boost pressures while resisting cracking or damage from extreme temperatures, making it ideal for both stock and modified applications. The kit also includes 3.0-inch mandrel-bent aluminum piping on the hot and cold sides, which eliminates the restrictive stock resonator and enhances flow by up to 55 percent. The CNC-machined quick-disconnect fittings, complete with new O-rings and spring clamps, allow for a seamless installation that maintains factory sensor and harness mounting points. Additionally, the pipes feature three tapped bungs, enabling easy installation of sensors or water/meth injection systems.
Whether you're upgrading for better performance or preparing for further modifications, this intercooler kit offers a significant upgrade over factory components, enhancing cooling capacity, airflow, and overall engine efficiency. Backed by Mishimoto’s lifetime warranty, it provides a reliable and durable solution for your 2017-2019 Chevrolet or GMC Duramax diesel truck. Installation is straightforward, and the kit fits seamlessly without modifications, making it an excellent choice for enthusiasts and professionals alike.
