Already running a Dual Pulley setup on your Audi 3.0T supercharged engine and looking for more?  IE's Throttle Body Upgrade kit removes the final power restriction from the factory equipped supercharger.

Release the complete power potential from your factory supercharger with an 80mm throttle body and matching IE software.

The larger throttle body is only one part of the equation, simply creating an adapter plate and bolting on a larger throttle body creates abrupt changes and inhibits air flow.   The included IE throttle adapter is cast and CNC machined from aerospace quality aluminum creating a smooth transition from the larger throttle body to the supercharger inlet.


  • 80mm diameter
  • Larger Throttle body 20% more flow over stock throttle
  • Up to 548 Horsepower on dual pully setup
  • No DIY wiring, plug and play harness included
