Experience ultimate performance with our Wagner tuning competition package for the Audi RS4 B9/ RS5 F5 consisting of the intercooler upgrade kit and the water cooler upgrade kit. Audi RS4 B9 331KW/450PS from 2017 Audi RS5 F5 331KW/450PS from 2017 onwards the intercooler upgrade kit 200001162 Our high-performance intercooler was specially developed for the demanding 2.9 liter V6 biturbo engine (VW EA839) of the Audi RS4/RS5 models. It replaces the standard water-cooled intercooler and offers you a multitude of advantages. With our new performance intercooler core, which measures 222 mm x 200 mm x 120 mm, we have increased the external core volume by an impressive 185%. The optimal ratio between the inner and outer cooling surface ensures maximum heat transfer and optimal internal airflow. The cast aluminum end boxes were designed in CAD and perfected with the help of CFD simulations. The result is outstanding cooling properties with minimal back pressure. Our high-performance intercooler is therefore also ideally suited for racing and ensures optimum cooling of the charged air with a significant increase in performance. For a long-lasting and reliable cooling effect, all our Wagner Tuning intercoolers are equipped with a thermally conductive anti-corrosion coating. Installation of the system is uncomplicated thanks to our detailed installation instructions and is carried out using the plug & play method. The advantages at a glance: - Significantly improved cooling performance for optimum power delivery - Minimized back pressure for optimized performance - More power and torque for a more intense driving experience - Mechanical relief of the turbocharger for a longer service life - 100% pressure resistance for maximum reliability - Simple and easy installation using the plug & play method - Up to 4-year warranty for a worry-free driving experience Take your Audi RS4/RS5 to a new level of performance with our WagnerTuning high-performance intercooler. Experience outstanding cooling performance and maximum performance in every race! The Wagner Tuning Performance Intercooler Kit fits the following models: Wagner Tuning Performance Intercooler Kit Audi RS4 B9 / RS5 F5 Core dimensions OEM intercooler: 220 mm x 100 mm x 85 mm V = 1.87 liters Mains dimensions Wagner Tuning intercooler: 222 mm x 200 mm x 120 mm V = 5.33 liters Part number: 200001162 Kit comes with: 1 intercooler 2 silicone air hoses 6 cooling water hoses 1 mounting material 1 installation instruction the radiator upgrade kit 400001012 The 2.9L V6 biturbo engine in these models is equipped with an advanced indirect charge air cooling circuit. Unlike conventional systems, the charge air cooling process is not realized by ambient air, but by a separate cooling water circuit. A reduction in the cooling water temperature therefore leads directly to an improved cooling performance of the charge air. This is where the advantages of the Wagner Tuning Upgrade water cooler come into their own. The newly developed competition racing core of the Wagner Tuning high-performance water cooler increases the radiator volume of the standard water cooler by an impressive 55%. The optimized ratio between the inner and outer cooling surface ensures maximum heat transfer and at the same time guarantees sufficient air flow for adjacent components such as the engine water cooler. In addition, the water coolers are equipped with a thermally conductive anti-corrosion coating that ensures a long-term cooling effect. Installation of the system is straightforward and virtually plug & play thanks to our user-friendly installation instructions. Experience the next level of performance with the Wagner Tuning Competition Water Cooler Kit for your Audi RS4 B9 / RS5 F5 suitable for the following vehicles : Audi RS4 B9 331KW/450PS from 2017 Audi RS5 F5 331KW/450PS from 2017 Dimensions OEM water cooler: 720 mm x 485 mm x 25 mm V = 8.73 liters A = 3492 cm² Wagner Tuning water cooler dimensions: 690 mm x 490 mm x 40 mm V = 13.52 liters A = 3381 cm² Part number 400001012
