Mishimoto 17-19 GM 6.6L L5P Hot-Side Pipe and Boot Kit Polished

Mishimoto is well-known for making well-built cooling components, and this hot-side intercooler pipe and boot kit is a great example for your 2017-2019 Chevrolet or GMC 6.6L Duramax L5P truck. The factory hot-side pipe is a restrictive 2.5 inches with tight bends and a built-in resonator that really chokes down airflow. This Mishimoto kit replaces that with a smooth, 3-inch diameter pipe that runs straight through, eliminating the resonator entirely to let your engine breathe much easier.

This improved airflow means more power potential for your truck. The pipe itself is made from mandrel-bent aluminum for smooth transitions and is polished to look sharp under the hood. Mishimoto includes their silicone boots featuring DuraCore™ technology, which is a special inner layer that resists heat, pressure, fuel, and oil better than standard silicone, helping to prevent leaks and blowouts over time. To ensure a solid connection, the kit comes with constant-tension T-bolt clamps that provide consistent holding power. It's designed as a direct bolt-on upgrade, making installation straightforward.

This kit is a direct bolt-on upgrade for your 2017-2019 Chevrolet Silverado 2500 HD, 3500 HD, or GMC Sierra 2500 HD, 3500 HD. It comes with a Mishimoto Lifetime Warranty, so you can be confident in its performance for years to come.
