Overview

This Mishimoto forced-induction upgrade is a direct-fit upgrade for 2017-2019 Chevrolet/GMC applications covering Sierra 2500 HD, Sierra 3500 HD, Silverado 2500 HD, Silverado 3500 HD. It replaces the weak points of the stock part with stronger materials and better flow or cooling so heat, boost and abuse stay under control on street and track duty. AutoTalent lists verified US-market fitment in the table below.

Why upgrade

Improve the power and efficiency of your 2017-2019 Chevrolet/GMC 6.6L Duramax L5P with our Mishimoto intercooler pipe and boot kit. The factory L5P intercooler pipes are a measly 2.5" diameter that chokes the engine, while tight bends and a resonator on the hot side create even more restriction. Mishimoto engineers these kits around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
