80mm Hemi Throttle Body Upgrade Kit

The Integrated Engineering IEINCG3A Throttle Body Upgrade Kit is engineered to unlock the full potential of your factory supercharger by eliminating the last significant power restriction. This kit directly replaces the stock throttle body with a larger 80mm unit, increasing flow by 20% over stock and enabling your supercharger to breathe more freely, especially in high-performance applications. The kit includes a precisely cast and CNC-machined aluminum adapter that ensures a smooth transition from the larger throttle body to the supercharger inlet, preventing airflow turbulence. Also included is a plug-and-play throttle harness, eliminating the need for any DIY wiring, and a reinforced silicone coupler for seamless integration with IE intake systems. This direct bolt-in design retains all factory parts and systems, and is port-matchable for ported superchargers. To realize the full benefits of this upgrade, an existing IE Stage 2 Dual Pulley Tune is required, and IE offers a free tune update for current customers. The system is designed for the Audi B8/B8.5 S4, S5, S5 Convertible, and C7 A6, A7 models equipped with the 3.0TFSI supercharged engine (non-CREC for A6/A7). Compatibility includes the 2009-2016 S4, 2013-2015 S5, 2008-2015 S5 Convertible, 2010-2016 A6, and 2010-2016 A7. An IE Cold Air Intake (hard pipe) is required for a no-modification installation.
