Mishimoto Intercooler Boot Kit for Duramax

The Mishimoto Intercooler Boot Kit for Duramax is a direct-fit silicone boot upgrade (also called intercooler hose or coupler kit) for the 6.6L Duramax diesel. It replaces the factory boots, which can fail under the heat and boost pressure of a modified diesel. The result is a more reliable charge-air system.

Key Features:

• DuraCore technology: This synthetic material forms the innermost layer of Mishimoto silicone diesel boots. Compared to normal silicone, it resists heat, pressure, fuel, and oil better.
• Longer boot life: The DuraCore inner layer helps prevent leaks and blowouts.
• Direct-fit design: The boots are made as direct replacements for the factory boots, so no modifications are needed.
• T-bolt clamps: Mishimoto constant-tension T-bolt clamps give accurate, consistent holding power.
• Lifetime warranty: The kit is backed by the Mishimoto Lifetime Warranty.

These boots work well alongside Mishimoto intercooler pipes and the Mishimoto performance intercooler. Together they give you a stronger, better-sealing boost system for daily driving, towing, or higher-power builds.
