The AFE 46-20118 BladeRunner Cold Side Intercooler Pipe is a 3"mandrel-bent replacement for your stock 2011-2016 GM 6.6L Duramax LML.

Perfect Fit:
Tube lines up directly to factory couplings for a convenient, tight and secure installation with minimal parts.

Flow and Performance:
The intercooler tube is constructed of 3"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. Also included, one 1/8" NPT port is provided for connecting a pressure sensor or water methanol injection. The smooth transition bends decrease turbulence and minimize pressure loss, while increasing horsepower and torque. Installs on the Cold-Side to transfer cooled air smoothly to the engine for better performance.

Installation is a snap:

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. Fits OEM or AFE's upgraded intercooler.

AFE Badging:
Unique stainless steel laser-cut AFE Power logo plate is welded-on for an aggressive style.
