Mishimoto 17-19 GM 6.6L L5P Cold-Side Pipe and Boot Kit Polished

Mishimoto is known for making well-built cooling components, and this cold-side intercooler pipe and boot kit is a great example for your 2017-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.6L Duramax L5P engine. The factory pipe can be a bottleneck, with its smaller 2.5-inch diameter and tight bends that restrict airflow. This Mishimoto kit upgrades you to a full 3-inch diameter pipe, which is mandrel-bent for smooth transitions. This significantly increases airflow, giving your engine more potential for power.

This kit is designed as a two-piece unit, similar to the factory setup, making installation straightforward. It comes with Mishimoto's silicone boots featuring DuraCore™ technology. This advanced material offers better resistance to heat, pressure, fuel, and oil compared to standard silicone, helping to prevent leaks and blowouts over time. To ensure a secure connection, the kit includes constant-tension T-bolt clamps for consistent holding power. You'll also get a CNC-machined quick-disconnect fitting with a new o-ring and spring clip for a leak-free seal. Importantly, this pipe retains the factory mounting location for the intake air temperature harness, keeping your wiring tidy and secure.

This is a direct bolt-on upgrade that comes in a polished finish. Mishimoto backs this kit with their Lifetime Warranty.
