GMC Sierra 3500 HD Intercooler Pipe and Boot Kit - Mishimoto - Mishimoto 6.6L Duramax, Includes hot-side and cold-side pipes with silicone boots and T-bolt clamps - Polished - `11-`15 free shipping

GMC Sierra 3500 HD Intercooler Pipe and Boot Kit - Mishimoto - Mishimoto 6.6L Duramax, Includes hot-side and cold-side pipes with silicone boots and T-bolt clamps - Polished - 2011-2015. A direct bolt-on upgrade for 6.6L Duramax trucks that replaces the factory restrictive piping with larger mandrel-bent tubes for improved flow.

This Mishimoto kit is built from mandrel-bent aluminum with a polished finish and includes both hot- and cold-side pipes plus silicone boots and constant-tension T-bolt clamps. The cold-side pipe measures 3.5 inches and the hot-side is 3.0 inches to reduce choke points found in OEM plumbing. Mishimoto DuraCore silicone is used on the boots for increased resistance to heat, pressure, fuel, and oil, reducing the risk of leaks or boot failures. The kit is made in the USA and comes with Mishimoto’s lifetime warranty. It pairs well with the Mishimoto 6.6L Duramax Performance Intercooler and is a straightforward upgrade for enthusiasts looking to improve airflow, responsiveness, and EGT management.

Features

  • Direct bolt-on mandrel-bent aluminum pipes (polished finish)
  • 3.5" cold-side and 3.0" hot-side pipe diameters
  • Mishimoto DuraCore silicone boots for heat and chemical resistance
  • Included constant-tension T-bolt clamps for consistent clamping force
  • Fits 2011–2015 Chevrolet/GMC 6.6L Duramax trucks (Silverado/Sierra 2500/3500 HD)
  • Made in the USA with Mishimoto lifetime warranty
