The GMC Sierra Intercooler Pipe and Boot Kit by Mishimoto is the essential upgrade for your 2017-2019 Chevrolet/GMC 6.6L Duramax L5P. This 3.0-inch mandrel-bent aluminum kit is designed to significantly enhance your vehicle's airflow, contributing to its power and efficiency. The polished finish not only ensures durability but also adds a touch of sophistication under the hood.

Upgrading from the restrictive factory 2.5-inch pipes, this kit features a full 3-inch diameter on both hot and cold sides, eliminating bottlenecks and maximizing airflow. The Mishimoto intercooler pipe also replaces the factory resonator with smooth transitions, resulting in up to 55% less restriction compared to stock pipes. This enhancement paves the way for a notable increase in power potential. Additionally, the DuraCore™ technology, used in the silicone boots, offers superior resistance to heat, pressure, fuel, and oil, effectively preventing leaks and blowouts.
