Mishimoto 17-19 GM L5P Duramax Intercooler Kit - Silver w/ Polished Pipes

If you're towing heavy loads or pushing your 2017-2019 6.6L Duramax L5P truck hard, you know how important keeping intake temperatures down is for performance and reliability. The factory intercooler system, while adequate for daily driving, can become a bottleneck when you really ask your truck to work. Mishimoto developed this performance intercooler kit specifically to address those limitations, giving your Duramax the improved cooling it needs to perform at its best, whether you're on the job site or on the open road.

This kit features a massive 68mm-thick bar-and-plate intercooler core, which is a full 70-percent thicker than the stock unit. This larger core, combined with cast-aluminum end tanks that have improved inlet and outlet designs, significantly reduces restriction by up to 64-percent. This means your engine gets cooler, denser air, which translates to better power and less strain on the turbo system. The kit also includes 3.0-inch mandrel-bent aluminum piping for both the hot and cold sides. These pipes replace the restrictive stock resonator and improve airflow by up to 55-percent over stock, all while fitting like a factory part thanks to CNC-machined fittings and provisions for all your factory sensors and harnesses. Plus, there are three bungs included if you ever decide to add sensors or a water/meth injection system down the line.

Installation is designed to be straightforward, with all the necessary components included to make it a direct fit for your 2017-2019 Chevrolet or GMC HD truck. This kit is a solid upgrade whether your truck is mostly stock or has been modified for more power. Mishimoto backs this kit with their signature Lifetime Warranty, giving you peace of mind for years of reliable service.
