Product Description

The aFe **46-20119 BladeRunner 3" Hot-Side Intercooler Tube** is a direct-fit performance upgrade designed for **2011-2016 Chevrolet Silverado and GMC Sierra heavy-duty trucks equipped with the 6.6L Duramax LML diesel engine**. This hot-side intercooler tube replaces the restrictive factory pipe with a **mandrel-bent 3" aluminum tube** that dramatically increases airflow, reduces turbulence, and decreases intake pressure loss to improve turbo efficiency and engine response.

Finished in a durable **wrinkle-black powder coat** for heat and corrosion resistance, the BladeRunner tube includes **heavy-duty 5-ply silicone couplings** and **stainless-steel constant-tension T-bolt clamps** for a secure, leak-free installation using all factory mounting locations. A built-in **1/8" NPT port** allows integration of a pressure sensor or water/methanol injection kit for advanced tuning. Ideal for enthusiasts seeking enhanced throttle response, increased horsepower and torque potential, and lowered exhaust gas temperatures, this intercooler upgrade adds both performance and style to your Duramax diesel platform.
