IE's throttle body upgrade kit for the supercharged Q5 & SQ5 removes the restrictive stock throttle body and replaces it with a free-flowing V8-sized monster. This complete plug-and-play kit is the last step to releasing the full power potential from your IE Stage 2 dual pulley setup and maxing out the performance potential from your supercharged 3.0TFSI engine.


This throttle body upgrade kit has been engineered for existing IE dual pulley tuned Audi Q5/SQ5 3.0T Supercharged engines. For S4, S5, A6, or A7 3.0T engines, see part number IEINCG3A

  • Includes cast aluminum and CNC machined adapter
  • Includes upgraded German Continental throttle body
  • Includes plug-and-play throttle harness
  • Includes reinforced silicone coupler for IE intake system
  • Includes free tune update for existing IE dual pully tunes
  • Releases max amount of power from dual pulley setups
  • 20% increase in flow over the stock throttle body
  • Smooth transition from inlet to throttle body
  • Same as stock operation
  • Direct bolt-in retains all factory parts and systems
  • Port matchable for a ported supercharger
  • Up to 548 horsepower on dual pulley setups


IE throttle body kit includes a new air intake inlet silicone adapter that directly fits IE's Cold Air Intakes. This coupler directly creates a perfect high-flow transition from the intake velocity stack to the new large throttle body. No modifications or extra adapters are required!

IE SQ5 cold air intake required for no-modification install


A larger throttle body only performs if the airflow is delivered correctly. A simple adapter plate creates an abrupt transition that inhibits airflow. The IE cast aluminum adapter was optimized with computer flow dynamics (CFD) software for the optimal path and shape to transition airflow speeds up air velocity with minimum turbulence smoothly.


IE engineers performed flow bench and power tests of multiple throttle bodies to determine the best size to include in our kit. While easier to fit, smaller 75mm throttle bodies do not completely open up the factory restriction, while more significant 84mm and 90mm throttle bodies result in no extra power gains. The included German made Continental throttle body offers the most power available from a size standpoint while allowing for an optimal-flow-designed adapter housing.



The stock-equipped throttle body is perfectly fine for stock pulley sizing and functions effectively on single pulley ratios. However, on higher power setups running supercharger/crank pulleys, heat exchangers, higher octanes, ethanol, etc., this small throttle becomes a big flow restriction for the supercharger. By increasing the size of the throttle body coupled with our smooth transition adapter, the supercharger and engine can breathe free and pull the required air demands from the intake system.
