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

If you’ve got a 2004.5–2005 LLY Duramax, chances are your factory intercooler hoses are starting to show their age. Cracks, leaks, soft spots—it happens. This Silicone Intercooler Hose Kit is the upgrade that takes care of all that. Whether you’re towing, tuned, or just putting in daily miles, these hoses are built to handle the pressure—literally.

Key Features

  • Multi-Layer Silicone That Lasts: These aren’t your average hoses. They’re layered up to handle high heat and boost without ballooning, cracking, or turning soft over time.
  • Oil-Resistant Material: Diesel engines see oil in the intake all the time. These hoses are built to resist oil breakdown, so you’re not chasing leaks every few months.
  • Drop-In Fit: No cutting, no custom mods—these hoses are shaped to match your stock setup. Bolt 'em in and go.
  • Heavy-Duty T-Bolt Clamps Included: You’ll get the right clamps in the box, strong enough to hold boost even when you're pushing hard.

Why Bother Upgrading?

Stock rubber hoses? They don't age well. Over time, they dry out and crack—which leads to boost leaks, lower power, hotter EGTs, and wasted fuel. If you're noticing a loss in performance, this might be why. This silicone hose kit seals things back up and stays that way. Even tuned trucks benefit big time from the extra durability and airflow consistency.

Compatibility

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

Install in No Time

No need for shop tools or fabrication. This kit installs using basic hand tools, and everything you need is in the box—hoses, clamps, and a clean fit. You'll spend less time under the hood and more time driving.

If you're ready to ditch the stock rubber for something stronger, this Silicone Intercooler Hose Kit is it. You’ll get better airflow, less hassle, and the kind of durability that just makes sense for any Duramax running hard.

Disclaimer: We recommend having a pro handle the install if you’re unsure. Double-check your fitment and make sure clamps are torqued properly for the best results.
