How does improved power, efficiency, and maximized flow sound for your 2017-2019 Chevrolet/GMC 6.6L Duramax L5P? You can get those benefits with Mishimoto’s intercooler pipe and boot kit. How so? Well, the factory L5P intercooler pipes are a measly 2.5" diameter that chokes the engine, while tight bends and a resonator on the hot side create even more restriction.

The difference is that Mishimoto’s intercooler pipes are 3" in diameter throughout with smooth transitions to significantly increase airflow, resulting in more power potential. The hot-side pipe also eliminates the stock resonator for maximum flow. Combined, the Mishimoto intercooler pipes are up to 55% 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 the Duramax, this kit also includes Mishimoto’s silicone boots with DuraCore technology. Mishimoto DuraCore technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of the 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. The 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, Mishimoto’s pipes retain the intake air temp harness mounting location for safe and secure wire routing, just as Chevy/GMC intended. The 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 Duramax products, this kit includes our Mishimoto Lifetime Warranty.

Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.

Wanting to correct my previous review (I reviewed the incorrect item). This product fit perfectly in my vehicle- my apologies for the first review; perhaps Amazon or the vendor can replace the first review with this one. I am very pleased with this item.
