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.

The concept is great, the item is sub par.
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
I bought this for a 2021 Silverado WT thinking I'd be able to screw this into the dash cubby as the adhesive wouldn't servive -50⁰ F Fairbanks winters. Beware, if you own this truck, you have to remove the entire dash assembly to include instrument cluster and infotainment system in order to screw this into the cubby. The cubby on this model is actually apart of the entire upper dash panel and cannot be removed separately as the instructions state. I decided I'd give the adhesive pad a try until I bought some self tapping screws but the mount is not contoured like my cubby, therefore it badly rocks. I don't recommend this to anyone with a 2021 Silverado WT unless they want to spend over 3 hours installing this.

Expected more for the price.

Arms are a bit short, and within a week, I could already feel the springs feeling a bit ridged. Holds well and does the job. Looks nice to!

Very nice fit and finish. Feels very high quality. Phone charges very quickly and doesn’t heat up as much. It charges through my heavy duty case that i thought i would have to replace as it doesn’t charge on other charges that ive tested. Very impressed.
