Product Description

The aFe **46-20138-B BladeRunner 3" Hot Side Intercooler Tube** is a high-flow performance upgrade designed specifically for **2013-2018 Ram 2500/3500 and select Ram 4500/5500 trucks** powered by the **6.7L Cummins I6 diesel engine**. This BladeRunner tube replaces the restrictive factory hot-side charge pipe with a **mandrel-bent 3" stainless steel tube**, allowing significantly smoother airflow from the turbo to the intercooler. The larger diameter and smooth bends reduce pressure loss and turbulence, improving turbo response and potentially increasing horsepower and torque outputs while helping to lower exhaust gas temperatures under boost conditions.

Finished in a durable **wrinkle-black powder coat** for enhanced heat resistance and corrosion protection, the tube includes **heavy-duty 5-ply silicone couplings** and **constant-tension stainless-steel T-bolt clamps** for a secure, leak-free fit via factory mounting points. The bold **aFe POWER laser-cut logo plate** adds visual appeal under the hood, while the direct-fit design simplifies installation with no cutting or modifications required. Note: this performance part is **not CARB exempt**, and may not be legal for sale/use in California or other restrictive states.
