Product Description

The aFe **46-20114-B BladeRunner Hot & Cold Intercooler Charge Pipe Kit** is a performance upgrade engineered for **2011-2016 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks** equipped with the **6.6L Duramax LML turbo diesel engine**. This kit replaces the factory intercooler tubes with **mandrel-bent 3" aluminum charge pipes** that significantly reduce airflow restriction and turbulence. With a smoother flow path and larger diameter compared to stock, these intercooler tubes help improve turbo efficiency, response, and overall engine performance.

Finished in a **wrinkle black powder coat**, the BladeRunner tubes not only resist corrosion and engine heat but also add under-hood visual appeal. The kit includes **premium high-temp silicone couplings** and **stainless-steel constant-tension T-bolt clamps** for secure, leak-free installation. Designed to work with either the OEM or aftermarket intercooler, this direct-fit kit uses all **factory mounting locations**, making installation straightforward without modifications. While not CARB legal in California and some states, this charge pipe upgrade is ideal for diesel enthusiasts seeking enhanced airflow and a performance edge.
