Enhance the performance and reliability of your 2017-2019 Chevrolet Silverado or GMC Duramax 6.6L L5P with the Mishimoto intercooler pipe and boot kit. Designed with precision, this kit replaces the restrictive factory piping, which is only 2.5 inches in diameter, with a 3-inch diameter mandrel-bent aluminum pipe that ensures smooth airflow. The larger diameter and seamless transitions significantly reduce airflow restrictions by up to 55 percent, unlocking more power potential from your diesel engine. The hot-side pipe also eliminates the stock resonator, further increasing exhaust flow and enhancing overall engine responsiveness.
Both the hot-side and cold-side pipes feature a two-piece design that simplifies installation, making it accessible for DIY enthusiasts and professional mechanics alike. The kit includes durable silicone boots reinforced with Mishimoto's proprietary DuraCore™ technology, offering superior resistance to heat, pressure, fuel, and oil. This enhanced durability prevents leaks and blowouts, extending the lifespan of the boots even under severe operating conditions. To ensure a secure fit, the kit is equipped with Mishimoto constant-tension T-bolt clamps and CNC-machined quick-disconnect fittings with O-rings and spring clips for a leak-free connection.
The cold-side pipe retains the factory intake air temp harness mounting point, maintaining factory wiring configurations while providing options for sensor installation through drilled and tapped bungs. The pipes are finished in either a polished or wrinkle black powder coat, allowing you to customize the look of your engine bay. As with all Mishimoto products, this intercooler pipe and boot kit is backed by a lifetime warranty, offering peace of mind and long-term performance. Whether you're seeking increased horsepower, improved airflow, or enhanced durability, this direct bolt-on upgrade is an excellent choice for your Duramax diesel truck.
