IE's Throttle Body Upgrade Kit has been engineered for existing Dual Pulley Tuned Audi 3.0T Supercharged engines. This complete bolt-on kit completely removes the removes the factory restrictive throttle body and replaces it with a much larger 80mm throttle body and cast adapter that creates a smooth transition from the air intake to the supercharger.
Pinch of Extra power
One of the most cost effective ways to gain another ~20hp out your Audi S4/S5. Installation was fairly straightforward and took less than 30 minutes including the tuning process. My only disappointment was the throttle body /w dual pulley tune (crackle) is not as prevalent and fierce as the regular dual pulley tune (crackle). If they make a patch for the throttle body /w dual pulley rune (crackle) to give that same effect I would gladly give them 5 stars. I may even remove the throttle body in the meantime just to get that effect back.
