GM Duramax 6.6L - Silicone Intercooler Hose Kit (2004.5–2005)

Replace your brittle, aging factory hoses with a performance-driven upgrade. This Silicone Intercooler Hose Kit is built to handle what your 2004.5–2005 LLY Duramax throws at it—heat, pressure, and time. Whether you're daily driving, towing heavy, or tuned for performance, these hoses won’t quit when things get hot.


Key Features:

  • Multi-Layer Silicone Construction: Built to endure high-heat and high-boost environments without cracking, splitting, or collapsing.
  • Oil-Resistant Design: Won’t break down from oil exposure like OEM rubber hoses, keeping your charge system sealed and efficient.
  • Direct Fit Replacement: Engineered to drop into place with no cutting or modification required—just bolt in and go.
  • Premium T-Bolt Clamps Included: Ensures a secure, leak-free seal even under peak boost.

Why Upgrade?

Stock intercooler hoses are the weak link in your boost system. Over time, factory rubber degrades—leading to cracks, leaks, and lost power. Our silicone replacement kit offers a high-performance solution built for durability, airflow, and peace of mind. Whether you're running stock or tuned, these hoses keep your boost where it belongs: inside the pipe.


Compatibility:

  • 2004.5 & 2005 GMC Sierra 2500HD/3500HD 6.6L Duramax LLY
  • 2004.5 & 2005 Chevy Silverado 2500HD/3500HD 6.6L Duramax LLY

Simple Installation:

Designed for a quick, straightforward install. This kit includes all necessary clamps and fits directly in place of OEM components—no guesswork, no fabrication. Spend less time wrenching and more time driving.


Upgrade your LLY with confidence. This Silicone Intercooler Hose Kit gives your Duramax the durability, airflow, and reliability it deserves—especially when it matters most.

Size: Single, Style: 1-Way 200A Fuse, Color: Square ANL Fuse Holder
As some other reviews have said the plastic does feel a little fragile, but I've never cracked one. I have three for my 1900 watt system and they have worked excellent for my application.
