Improve the power and efficiency of your 2017-2019 Chevrolet/GMC 6.6L Duramax L5P with our Mishimoto intercooler pipe and boot kit. The factory L5P intercooler pipes are a measly 2.5in diameter that chokes the engine, while tight bends and a resonator on the hot side create even more restriction.The Mishimoto intercooler pipes are 3in in diameter throughout with smooth transitions to significantly increase airflow, resulting in more power potential. Our hot-side pipe also eliminates the stock resonator for maximum flow. Combined, the Mishimoto intercooler pipes are up to 55-percent less restrictive than stock.Both the hot-side and cold-side utilize a two-piece design for ease of install. To connect the pipes to our Duramax, this kit also includes our silicone boots with DuraCore(TM) technology. Mishimoto DuraCore(TM) technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore(TM) provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts.To add even more reliability, this kit includes Mishimoto constant-tension T-bolt clamps for accurate and consistent holding power. Our cold-side intercooler pipes also feature a CNC-machined quick-disconnect fitting with new O-ring and spring clip to ensure a secure and leak-free fit. Unlike other available pipes on the market, our pipes retain the intake air temp harness mounting location for safe and secure wire routing, just as Chevy/GMC intended. Our intercooler pipes also incorporate two bungs that can be drilled and tapped for sensors, so you can easily monitor your L5P's performance.The Mishimoto 2017-2019 Chevrolet/GMC 6.6L Duramax L5P intercooler pipe and boot kit is a direct bolt-on upgrade and is available in a polished or wrinkle black powder coated finish. Like all our Duramax products, this kit includes our Mishimoto Lifetime Warranty.Shipping Notes

Great fit for a 2005 Honda Element
These fit my 2005 Honda Element perfectly. Solved a small leak issue. I’ve had these installed for about one season so far (winter into summer) and they are still holding up.
The install is simple if you’re confident working on your power steering system.
Overall happy. No complaints
