Probably will not work. You may not know this but the RS4 has a 3 stage cyclonic separator that is supposed to work like a catch can. The RS4 also has a mesh material in the valve covers to help capture the oil vapor as well. Audi definitely knew about this as you can see in their patents and tried to run the motor in a stratified lean burn mode to help clean the valves. They changed this for some reason.To learn more click here:Audi RS4 Engine Design Study Guide Refer to page 9.There have been a few folks who have added catch cans to the RS4 and it has not worked. Using oils with higher flash points seems to mitigate the problem somewhat, which is why I switched to RLI BIOSyn oil. In addition, I have changed my oil service interval to 3000miles to eliminate as much buildup as possible versus the factory recommended 10k mile intervals. We will see how these steps help the buildup in December when I take apart the intake manifold.This is really the only problem with the RS4. DRC can be replaced with an incredible Ohlins setup from Stasis or the newer revision factory parts, which I have. Despite the CB hassle the car is so much fun to drive and plenty fast.Good luck with the S4. Hopefully, the carbon bug does not hit the B8 S4 models. Pretty soon your S4 will be faster then your SC NSX. From a dig it will definitely take a stock NSX as it sits today.
