Constructed of 2" into 2-1/2" mandrel-bent aluminum tubing for maximum flow then powder-coated wrinkle-black for heat and corrosion resistance. The smooth transition bends decrease turbulence and minimize pressure loss, while increasing horsepower and torque. Installs on the Hot-Side to transfer heated air smoothly to the intercooler to accelerate heat transfer for better performance. Utilizes the factory mounting locations for a hassle-free installation. Includes high quality stainless steel clamps and heavy-duty 5-ply couplings for strength. Fits OEM or aFe's upgraded intercooler (46-20201). A unique laser-cut aFe POWER logo plate is welded on for an aggressive style.
