Description
The Mishimoto cold-side intercooler pipe and boot kit (MMICP-DMAX-17CWBK) replaces the restrictive factory 2.5in cold-side pipe on the 2017-2019 6.6L Duramax L5P with a 3in mandrel-bent aluminum pipe finished in black powder coat, engineered as a two-piece assembly for a straightforward, direct bolt-on install. This is a forced induction upgrade purpose-built for the L5P, not a generic piece of induction system tubing repurposed from another platform.
Where the stock cold-side pipe chokes airflow with tight bends and an undersized 2.5in diameter, Mishimoto’s mandrel-bent design runs a full 3in with smooth transitions the entire length, delivering up to 16-percent less restriction than the factory piping in this forced induction system. The kit pairs the pipe with Mishimoto silicone boots built with DuraCore technology, a synthetic innermost layer that offers superior resistance to heat, pressure, fuel, and oil compared to standard silicone, extending boot life and helping prevent leaks and blowouts. Mishimoto constant-tension T-bolt clamps hold everything together with accurate, consistent clamping force, while a CNC-machined quick-disconnect fitting with a new o-ring and spring clip keeps the connection secure and leak-free. An internal bead roll locks the coupler to the throttle valve, and the design eliminates the failure-prone stock throttle valve connector while retaining the factory intake air temp sensor harness mounting location for safe, factory-style wire routing. No additional tuning is required after installation.

Frequently Asked Questions
What vehicles does this Mishimoto cold-side intercooler pipe kit fit?
This kit is a direct fit for the 2017-2019 Chevrolet Silverado 2500 HD, 2017-2019 Chevrolet Silverado 3500 HD, 2017-2019 GMC Sierra 2500 HD, and 2017-2019 GMC Sierra 3500 HD, all equipped with the 6.6L Duramax L5P engine.
How does the Mishimoto pipe compare to the factory cold-side pipe?
The factory cold-side pipe on the L5P is 2.5in in diameter with tight, restrictive bends. The Mishimoto pipe is 3in in diameter throughout with smooth mandrel-bent transitions, resulting in up to 16-percent less restriction than the stock piping.
Does installing this kit require any additional tuning?
No, this kit requires no additional tuning.
What is included in the Mishimoto cold-side intercooler pipe and boot kit?
The kit includes one aluminum intercooler pipe with a bung, one aluminum intercooler pipe with an O-ring and spring clip, two silicone boots with DuraCore technology, four constant-tension T-bolt clamps, and the Mishimoto Lifetime Warranty.
What finish does this specific kit come in?
This kit (MMICP-DMAX-17CWBK) is finished in black powder coating; Mishimoto also offers this cold-side pipe and boot kit in a polished finish.
What torque should be used on the included clamps during installation?
Mishimoto recommends 27 in-lbs (3NM) for the T-bolt and constant-tension T-bolt clamps, with an operating range of 18-35 in-lbs (2-4NM). Do not exceed the maximum torque rating of 35 in-lbs (4NM).
