The competition package for the Audi TTRS 8S consists of the intercooler upgrade kit EVO 3 and the downpipe kit with 2 additional cat pipes (200CPSI). Intercooler Upgrade Kit 200001136 The high-performance intercooler has the following core dimensions (515mm x 367mm x 95mm [stepped] = 16,500cm³) and thus offers an 84% larger inflow area and 101% more charge air volume compared to the original intercooler. The newly developed competition high-performance intercooler Core ensures sufficient airflow to the adjacent components, such as the water cooler. It is a high-quality Tube Fin core with internal turbulators. The end boxes of the intercooler are made of cast aluminium and have been optimized using flow analyses in the CFD system. Integrated air baffles at the inlet ensure that the charge air cooler is filled evenly. The result is excellent cooling properties with minimal back pressure. This kit is therefore suitable for racing. In addition, all our intercoolers have an anti-corrosion coating with heat conduction properties. This guarantees long-lasting and optimum cooling with a significant increase in performance. The intercooler and the original crossbar form a stable unit and, thanks to the new Competition high-performance intercooler core, weighs just 11.7 kg. It is fitted to the original mounting points and is easy to install (see installation instructions for minor adjustments). Tested and pressure-resistant up to 6 bar. All our products are subject to constant quality control.
