The performance package for the BMW E60-series 535d 635d consists of the intercooler upgrade kit, the downpipe kit and fits the following vehicles. BMW E60/61 535d E60/E61 210KW/286PS (2006-2009) BMW E63/64 635d E63/E64 210KW/286PS (2006-2010) Intercooler Upgrade Kit 200001060 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 aluminium 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 (plug & play), using the stock plumbing. No cutting or bumper removal required. Fitment is easy, replacing the OEM intercooler. All of our products undergo rigorous quality control.
