APR Ultracharger Throttle Body Upgrade Audi S4, S5 3.0 TFSI MS100128
​​
80MM THROTTLE UPGRADE
 
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
 
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 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 dam 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.
 
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.
 
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.
