Mishimoto Hot-Side Intercooler Pipe & Boot Kit – 2017-2019 L5P Duramax

Mishimoto’s 3-inch hot-side intercooler pipe and boot kit boosts airflow up to 55% over stock for 2017-2019 Chevrolet/GMC 6.6L Duramax L5P trucks.

Description

The Mishimoto MMICP-DMAX-17HP hot-side intercooler pipe and boot kit is purpose-built for the 2017-2019 Chevrolet/GMC 6.6L Duramax L5P, replacing the factory’s restrictive 2.5-inch hot-side piping with a full 3-inch diameter aluminum pipe that eliminates the built-in resonator and the tight factory bends that choke airflow. Designed as a two-piece pipe just like the factory setup, it’s engineered for a straightforward, direct bolt-on install without requiring additional tuning.

By opening up the hot-side path of your forced induction system, this Mishimoto kit reduces restriction versus the factory pipe by up to 55 percent, giving your induction engine more breathing room and more power potential. This isn’t a generic forced induction turbo accessory or a catch-all induction system upgrade — it’s a Duramax L5P-specific solution that pairs a mandrel-bent 3-inch aluminum pipe with Mishimoto silicone boots featuring DuraCore(TM) technology, a synthetic inner layer that resists heat, pressure, fuel, and oil far better than standard silicone, extending boot life and helping prevent leaks or blowouts. Mishimoto constant-tension T-bolt clamps back up every connection for consistent, reliable holding power over time, and an included bung can be drilled and tapped for additional sensors if your setup calls for it.

Vehicle Applications

This hot-side intercooler pipe and boot kit is a direct bolt-on fit for the 2017-2019 Chevrolet Silverado 2500 HD and Silverado 3500 HD equipped with the 6.6L Duramax L5P, as well as the 2017-2019 GMC Sierra 2500 HD and Sierra 3500 HD with the same 6.6L Duramax L5P engine. Coverage spans these model years and trims exactly, so owners of L5P-equipped HD trucks from this window can install the kit without modification.
