This Performance intercooler has the following core size (530mm x 244[134]mm x 150[50]mm / stepped = 13.500 cm³), providing a 87% larger frontal area and 95% more volume compared to the original intercooler. Our engineers have increased the intercooler core size and efficiency, as well as improved the end tank design to remove any OEM bottlenecks, resulting in increased flow rating and charge cooling properties. High-performance Intercooler core with turbulators in a stepped design (weight: 9,8kg). Constructed of the highest quality Bar and Plate intercooler cores combined with cast aluminum optimized by CAD. Flow analyses and simulations were created to optimise the design for best possible Internal Airflow. This intercooler is the best choice when it comes to performance gains and low intake temperatures. A lot less pressure drop then OEM Intercooler. Anti Corrosion protective Coating with perfect thermal heat dissipating character. Optimal cooling with clearly more power. Kit is ready for installation, using the stock plumbing. No bumper removal required. Fitment is easy, replacing the OEM intercooler. All of our products undergo rigorous quality control.
