The BladeRunner GT Series Intercooler Kit increases airflow by 10% over stock and is constructed from the highest quality materials available. TIG -welded for increased durability, the GT Series Intercooler Kit will continue to perform at a high level in any driving condition. The BladeRunner intercooler tubes are constructed from 3” hot side and 3-1/2” cold side mandrel-bent aluminum tubing for superior flow. The high-temp wrinkle-black powder-coat insulates the tubes from engine heat and protects them from corrosion and damage. Smooth transition bends decrease turbulence and minimize pressure loss which increases horsepower and torque.
