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

When you're looking to get the most out of your 2017-2019 6.6L Duramax L5P truck, especially when it's hauling heavy loads or tuned for more power, the factory intercooler system can become a bottleneck. This Mishimoto Performance Intercooler Kit is designed to replace that stock system with a much more capable setup. You'll receive a massive 68mm-thick bar-and-plate intercooler core, complete hot-side and cold-side intercooler piping, and DuraCore boots, all in one package.

The heart of this kit is the substantially larger intercooler core, which is 70-percent thicker than the original equipment. This bigger core, combined with cast-aluminum end tanks featuring larger inlets and outlets, significantly reduces restriction by over 64-percent. This means your engine gets cooler, denser air, which is crucial for maintaining performance under demanding conditions. The included 3.0-inch mandrel-bent aluminum piping also plays a key role, eliminating the restrictive stock resonator and improving flow by up to 55-percent. Mishimoto has ensured this piping fits like stock, with CNC-machined fittings, bead-rolled ends, and mounting locations for your factory sensors and harnesses. Plus, there are three bungs ready for you to tap for additional sensors or a water/meth injection system.

This kit is a direct fit for your 2017-2019 Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, or GMC Sierra 3500 HD. It's a solid upgrade whether your truck is mostly stock or has been significantly modified. Mishimoto backs this kit with their signature Lifetime Warranty, giving you peace of mind for years of reliable service.
