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 (free upgrade for existing Dual Pulley customers).

• Larger Throttle Body 20% More Flow Over Stock Throttle
• Up To 548 Horsepower On Dual Pulley Setup
  
• No Diy Wiring Plug & Play Harness Included

• Maxes out horsepower and torque on dual pulley setups
• Includes everything needed to bolt on 80mm throttle body
• Free tune upgrade included with IE Dual Pulley Tunes
• Direct fit install with IE Cold Air Intakes
• High flow CNC machined cast aluminum throttle adapter 
• Plug and play throttle body harness included

Flawless Install

Your new throttle body kit includes a new air intake inlet silicone adapter that is a direct fit to IE's Cold Air Intakes. This creates a perfect high-flow transition from the intake velocity stack directly to the new 80mm throttle body. No modifications or extra adapters required!

*IE Cold Air Intake (hard pipe) required for no-modification install

Your Stock Throttle Is Robbing You Off Power

Your factory-installed throttle body has a smaller inlet than the supercharger that functions perfectly fine on stock power levels. However, on higher power setups running dual pulleys, heat exchangers, higher octanes, and Stage 2 Dual Pulley ECU calibrations this small restriction becomes a major damn for airflow unable to keep up with aftermarket performance parts requesting more flow.  By increasing the size of the throttle body with our smooth transition cast-aluminum adapter the supercharger can fully breathe to its utmost capability.

Size Matters

Before the design phase, engineers performed flow bench and power tests of multiple throttle body sizes to determine the best throttle body size to include in our kit. This is a delicate balance. While easier to fit, smaller throttle bodies do not completely open up the factory restriction while larger 90mm throttle bodies resulted in no extra power gains. The included 80mm throttle body offers the most power available from a size standpoint when upgrading your throttle body.

Size is nothing without flow

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

Free ECU Tune Calibration

Throttle body upgrades require matching ECU software to run and perform correctly. IE's Throttle Body ECU Tune is available as a free upgrade for all existing IE Stage 2 Dual Pulley owners. Don't already own IE Dual Pulley? The Throttle Body update is also included with all Dual Pulley tunes when purchased at no additional cost.

Stock Operation

Your car will be up and running in no time, by simply flashing the Throttle Body Upgrade software and plugging in the new throttle body with the included extension harness. There are no electrical trick boxes or funky harnesses to give you issues.
