Overview

This Mishimoto performance part is a direct-fit upgrade for 2017-2019 Chevrolet applications covering 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

Mishimoto is proud to release a direct-fit silicone boot kit with DuraCore™ technology designed specifically for the 2017-2019 Chevrolet/GMC 6.6L L5P Duramax. Mishimoto DuraCore™ technology is a synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. 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.
