Mishimoto Boot Kit DuraCore Direct Fit 2017-2019 6.6L L5P

Provide a direct-fit silicone replacement for the charge-air/turbo inlet boots with the Mishimoto Boot Kit DuraCore Direct Fit 2017-2019 6.6L L5P, delivering OEM-style fitment and the engineered DuraCore™ innermost layer for consistent material construction and installation reliability.

This Mishimoto kit is designed specifically for 2017–2019 Chevrolet and GMC trucks equipped with the 6.6L L5P Duramax engine. Mishimoto DuraCore™ technology refers to a synthetic material that comprises the innermost layer of the silicone boots, incorporated to control the boot’s core material properties.

Key technical features

• Direct-fit silicone boot kit — Provides one-to-one compatibility with factory locations and mounting points for straightforward replacement without modification.
• DuraCore™ innermost layer — Uses a synthetic inner layer as the core material component of the boot construction to define the internal material characteristic of the silicone assembly.
• Vehicle-specific design — Engineered for the 2017–2019 Chevrolet/GMC 6.6L L5P Duramax application to match routing and clearances found in the factory installation.
• Mishimoto brand engineering — Developed by Mishimoto with focus on component-level materials and fitment for diesel boot replacements and turbo upgrade service applications.

Why these features matter

Direct-fit compatibility reduces installation time and eliminates the need for trimming or modification, helping maintain factory routing and clearances. The defined DuraCore™ innermost layer standardizes the core material used inside the silicone construction, ensuring consistent manufacturing characteristics across the kit. Vehicle-specific engineering preserves OEM interfaces and supports straightforward integration with factory clamps and hardware.

Application notes

Intended as a factory-replacement style silicone boot kit for charge-air and turbo inlet locations on the specified 6.6L L5P Duramax model years. Use with existing factory clamps and mounting hardware unless otherwise specified by installation instructions.
