definitely do the spacers. We talked about it somewhere, but I was just saying how I really notice how FAST the car suffers from the heat and from repeated runs etc. I had the same problems with my S4, but the JHM intake spacers, whatever little bit of wizardry they did, really helped on that car. Apparently the RS4 is even more sensitive to intake air temps, and on top of that the spacers are a more effective design than on the S4 (they’re a bit thicker).
Win win really.
We should get a log of your car to see how it’s running now, then compare it when your carbon clean is done, and again when the tune is done so you can see the respective performance jumps.
