The 3-inch CTS Turbo intake system is designed for vehicles with a 2.0T FSI engine and software that requires a 3-inch mass air flow sensor (MAF).
Important: The kit is most commonly used with GIAC “Extreme File” software for K04 conversions and will not work with most standard software calibrations. Before purchasing, check with your software provider whether the calibration is compatible with a 3-inch MAF.
