aFe BladeRunner 3-Inch Aluminum Hot and Cold Intercooler Charge Pipe Kit, Black, Part Number 46-20114-B, for 2011–2016 GM 6.6L Duramax Diesel Trucks

Utilizes the factory mounting locations for a hassle-free installation. Includes high quality stainless steel T-bolt clamps and heavy-duty 5-Ply polyester reinforced couplings for strength and durability. The tubes also work with OEM or aFe's upgraded intercooler (46-20111). aFe Power's intercooler tubes are constructed from 3" (hot side) and 3" (cold side) mandrel-bent aluminum tubing for maximum flow then, powder-coated for a nice finish. The high-temp wrinkle-black powder-coating also insulates the tubes from engine heat and protects the tube from corrosion. The smooth transition bends decrease turbulence, minimize pressure loss, while increasing horsepower and torque. A unique laser-cut aFe Power logo plate is welded-on for an aggressive style.

Upgrade the charge-air system in your GM 6.6L Duramax diesel truck with the aFe BladeRunner 3-Inch Aluminum Hot and Cold Intercooler Tube Kit, part number 46-20114-B. Designed for 2011–2016 applications equipped with the LML engine, this kit replaces the restrictive factory intercooler tubes with smooth, mandrel-bent aluminum tubing engineered to improve airflow and reduce turbulence. The tubes are sized for efficient hot-side and cold-side performance and outflow the stock intercooler tubes by up to 15%.

The aFe BladeRunner intercooler tubes use factory mounting locations for a straightforward installation without unnecessary modifications. Premium stainless steel T-bolt clamps and heavy-duty 5-ply polyester-reinforced silicone couplings provide a secure connection, long-term durability, and a precise fit. The kit is compatible with either the original equipment intercooler or the aFe upgraded intercooler, part number 46-20111.

Each tube is finished in high-temperature wrinkle-black powder coating to help insulate the tubing from engine-bay heat while protecting the aluminum from corrosion. Smooth transition bends help minimize pressure loss and support improved horsepower and torque potential. A welded, laser-cut aFe Power logo plate adds a distinctive appearance under the hood. This automotive performance component is intended for off-road or competition use where emissions regulations apply; verify local requirements before installation.
