Why upgrade

A blown intercooler boot can mean the end to a weekend at the drag strip or a canceled day on the boat. You demand a lot from your truck, so you need reliable and dependable parts. Mishimoto is proud to expand their line of Duramax performance parts to include a direct-fit silicone boot kit with DuraCore™ technology designed specifically for the 6. 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.
