The aFe intercooler tube represents the next generation of Diesel performance products. Included is one 1/8" NPT bung for additional sensor or injection port. Tube comes complete with 4-ply heavy duty silicon couplers and constant tension T-bolt clamps for a tight and secure installation. Silicone Couplers with beads are used for a leak-free seal. No blowouts with this coupler. The intercooler tube is constructed of 3" mandrel bent powder-coated stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.
