Mishimoto intercooler pipe and boot kit for the 2017-2019 Chevrolet Silverado and GMC Sierra 2500/3500 HD 6.6L Duramax L5P. Replaces the choked 2.5in stock pipes with smooth 3in mandrel-bent aluminum, deleting the hot-side resonator to run up to 55% less restrictive than stock. Two-piece hot- and cold-side design eases install; cold-side uses a CNC quick-disconnect with new O-ring and spring clip, and the IAT harness mount is retained. Includes DuraCore silicone boots and constant-tension T-bolt clamps. Wrinkle-black finish. Lifetime warranty.
