Chevrolet Silverado 3500 HD Intercooler Boot Kit - Mishimoto - Hot-Side Boot Kit with DuraCore technology - ’11–’14. This direct-fit hot-side boot kit is built for the 6.6L LML Duramax in 2011–2014 Silverado 3500 HD pickups, designed to replace aging factory boots and improve reliability under boost.

The Mishimoto hot-side boot kit uses DuraCore technology in the innermost layer to resist heat, pressure, fuel, and oil that can cause premature failure in stock boots. Multiple silicone layers provide mechanical strength and blowout prevention while preserving factory fitment for a straightforward installation. The kit includes Mishimoto constant-tension T-bolt clamps to deliver consistent holding power under repeated thermal cycles and boost changes. For enthusiasts building higher-output trucks or anyone seeking a durable replacement for worn hoses, this kit offers a durable, serviceable solution that reduces the likelihood of boost leaks and downtime.
