you need to find out the code, mostly likely has something to do with the CAI since u just put it in not so long ago...
that why i stay away from the engine mods.....

Do you have Nav? When my CEL came up last week, the Nav was able to provide the code, but I'm not sure if that's specific to Nav or what (I'm still new to the UA6/7). If not, Autozone and other parts places will typically scan if for you for free.

If it's a name brand CAI, it shouldn't cause a code itself. Most likely there's a leak somewhere from the install, possibly around the flexible connection. Look over all of it real closely.

Check the connection for the sensor on the throttle body and the IAT sensor on the Inatke Manifold. Might be/have come loose.

Did they relocate the IAT?

mine came on after i removed the intake box to switch the filter... i disconnected the MAF sensor assembly on top of the throttle body and a tube that was on the back side of the intake tube i believe it goes to the back side of the engine (maybe its to the vacuum) im not sure.. when i was done i put it all back together turned the car on and the engine light came on.. went back unplugged the sensor blew on it and plugged it in, i noticed i may had pushed the tube too far in and pulled it out a bit, fixed that turned the car back on the light was gone... maybe that'll fix it for you as well, check you sensor and your tube
