Upgrade your 2017-2019 Chevrolet or GMC 6.6L Duramax L5P with the Mishimoto intercooler pipe and boot kit, designed to enhance airflow and boost engine performance. The factory pipes are limited by a 2.5-inch diameter and restrictive bends, which hinder optimal airflow and power output. Mishimoto’s solution features 3-inch diameter mandrel-bent aluminum pipes that maintain a smooth path for air, reducing restrictions by up to 55 percent compared to stock components. The hot-side pipe also eliminates the stock resonator, further increasing airflow efficiency and engine responsiveness. This upgrade facilitates more power potential and improved throttle response, making it an attractive choice for enthusiasts seeking reliable performance enhancements.
Both the hot-side and cold-side pipes utilize a two-piece design for straightforward installation. The kit includes high-quality silicone boots with Mishimoto’s proprietary DuraCore™ technology, providing excellent resistance to heat, pressure, fuel, and oil, which extends the lifespan of the boots and prevents leaks or blowouts. Mishimoto’s constant-tension T-bolt clamps ensure secure, even pressure across connections, while the CNC-machined quick-disconnect fittings with new O-rings and spring clips guarantee a leak-free fit. The pipes also retain the factory intake air temp harness mounting location for safe and proper wire routing, preserving the OEM wiring setup.
Designed with versatility in mind, the intercooler pipes feature two tapped bungs for sensors, allowing easy monitoring of your engine’s performance. The kit is available in a polished or wrinkle black powder-coated finish, providing options to match your vehicle’s aesthetic. As a direct bolt-on upgrade, it offers a simple installation process that does not require modifications. Backed by Mishimoto’s Lifetime Warranty, this kit delivers durability and peace of mind for your Duramax diesel truck, maximizing airflow and overall engine efficiency.
