Mishimoto's cold-side intercooler pipe and boot kit for 2017–2019 Chevrolet/GMC 6.6L Duramax L5P replaces the restrictive factory 2.5in pipe with a 3.0in mandrel-bent aluminum assembly and silicone boots featuring DuraCore™ for improved resistance to heat, pressure, fuel and oil. The two-piece, direct bolt-on design includes constant-tension T-bolt clamps and a CNC quick-disconnect fitting for leak-free installation.
