Mishimoto 17-19 GM 6.6L L5P Hot-Side Pipe and Boot Kit Polished
Boost power and efficiency on 2017-2019 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks with 6.6L Duramax L5P diesel engines using this Mishimoto hot-side intercooler pipe and boot kit. The factory 2.5in pipe with tight bends and resonator limits airflow while this 3in diameter design eliminates restrictions for greater flow and power gains. Split into two pieces like the OEM part it installs directly with included silicone boots and clamps.
Key Features

- Resonator Delete Design: Removes built-in factory restriction to enhance exhaust gas flow efficiency and engine performance
- Silicone Boots with DuraCore Technology: Inner synthetic layer resists heat pressure fuel and oil better than standard silicone to prevent leaks and extend boot life
- Constant-Tension T-Bolt Clamps: Stainless steel clamps deliver secure consistent sealing under high boost conditions
- Polished T6 6061 Aluminum Finish: Durable corrosion-resistant coating with direct bolt-on fit available also in wrinkle-black powder coat
Product Notes
- Direct bolt-on upgrade requires no cutting or modifications
- Includes all necessary boots hardware and clamps for complete installation
- Covered by Mishimoto Lifetime Warranty for long-term reliability
Installation Notes
- Professional installation recommended.
- Two-piece pipe design matches factory layout for straightforward replacement
