The GM CAI comes with an ECM calibration included to prevent a lean MAF reading. If your dealer uses a VIN for a 2018 or newer V6 instead of a 2016-17 when they reflash the ECM, they’ll get an error from GM saying it can’t be installed. The Chevrolet Performance page explicitly states their CAI is for 2016-2017 V6 only. Doesn’t seem to make sense, but for whatever reason you can’t install a CAI in a 2018 V6 and keep your warranty. Not even GM’s own part.
