2017 RS4 B9 331KW/450PS Intercooler Upgrade Kit and the Radiator Upgrade Kit

The competition package for the Audi RS4 B9 consists the Intercooler Upgrade Kit and the Radiator Upgrade Kit Audi RS4 B9 331KW/450PS from 2017 Audi RS5 F5 331KW/450PS from 2017The 2.9 Liter V6 biturbo engine (VW EA839) of RS4 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is realized by a watercooled intercooler which will be replaced. The high-performance intercooler has got a new performance core with the external core dimensions 222 mm x 200 mm x 120 mm / 8,74Inch x 7,87Inch x 4,72Inch. This intercooler core was directly developed for the high requirements of the RS4/RS5 engine and offers 185 % more external core volume compared to the stock intercooler. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and at the same time the best possible internal air flow. The aluminum cast endtanks were designed in CAD and optimized in CFD simulations.
