Audi's 2019 and newer model year 2.5T engines are equipped with a factory updated style diverter valve housing that is non-compatible with IE's Carbon Fiber Intake design. Installing an aftermarket intake on all newer configurations requires this additional IE Diverter Valve Adapter Kit for installation (sold separately). If your RS model is year 2019 or newer, make sure to pick one of these up for a simple install.
