Description
The Mishimoto MMICP-DMAX-17KP intercooler pipe and boot kit is a purpose-built forced induction upgrade engineered specifically for the 2017-2019 Chevrolet/GMC 6.6L Duramax L5P. Where the factory piping chokes airflow down to a measly 2.5-inch diameter with tight bends and a restrictive hot-side resonator, this Mishimoto kit opens things up with 3-inch mandrel-bent aluminum pipes and smooth transitions throughout, cutting restriction by up to 55 percent versus stock.
As a complete induction system upgrade, this kit pairs the redesigned hot-side and cold-side pipes with Mishimoto silicone boots featuring DuraCore technology, a synthetic inner-layer material that resists heat, pressure, fuel, and oil better than standard silicone to extend boot life and prevent leaks or blowouts. Mishimoto constant-tension T-bolt clamps deliver accurate, consistent holding power at every connection, while a CNC-machined quick-disconnect fitting with new O-ring and spring clip keeps the cold-side connection secure and leak-free. For anyone chasing more usable airflow and power potential from their forced induction setup without chasing down a full retune, this pipe and boot kit is a direct, bolt-on way to unrestrict the L5P’s charge-air path.
Vehicle Applications
This Mishimoto intercooler pipe and boot kit is a direct bolt-on fit for the 2017-2019 Chevrolet Silverado 2500 HD and 3500 HD equipped with the 6.6L Duramax L5P, as well as the 2017-2019 GMC Sierra 2500 HD and 3500 HD with the same 6.6L Duramax L5P engine. No other years, makes, or models are supported by this kit.
