INTAKE NOTES

Due to the larger turbo inlet of the RS7 turbos, both iE S6/S7 and RS7 air intake systems will require additional parts for installation, as outlined below.

For existing iE S6/S7 Air Intake Systems (IEINCN3), the airbox can be adapted using aftermarket RS7 turbo inlet adapter hose couplers -such as ECS Tuning part number 4348853, available with ECS Tuning RS7 turbo inlets Part Number 4460456.

For iE RS7 Air Intake Systems (IEINCX1), the intake will require two sections of 2.5" ID X 6" long generic silicone couplers. To achieve a cleaner factory look, consider sourcing two of the larger factory C7 RS7 inlet hose couplers instead. These are available under OE Part Number 079129740H (X2) to complete the installation.

STAGE 3 TRANSMISSION TUNE

The iE Stage 3 ECU tune surpasses the factory-set transmission torque limit and requires a matching transmission control unit (TCU) tune calibration. Our corresponding Stage 3 TCU tune synchronizes the transmission characteristics to match the larger turbo profiles, incorporating optimized shift points. As you progress through each gear, the DSG will shift at specific RPMs tailored to optimize the RS7 turbo powerband for the fastest acceleration on the road, track, or drag strip. These optimized shift points are active in both Drive mode and Sport Mode. Additionally, you will retain complete manual control of your shift points up to 6800RPM in manual/paddle shift mode.
