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!

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.

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.

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.

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.
