Made enquiries to MRC Tuning regarding a supercharger kit to fit the S4. They said that their TTS developed kit fits the RS4 and S5 but not the S4. I always thought that essentially they were the same engine.
So the question is, what would i need to swap in order to get the RS4 supercharger kit to fit the S4?
Thanks in advance.
