Any CAI that increases the MAF tube housing and does not implement any other compensation will lean out. You just can't increase the area and keep the same amount of air mass flowing over the sensor.
The AFR here isn't a risk. If you were to get a tune done your probably lean it out a comparable amount anyways.
Mishimoto did a great job paying attention to the MAF response. They can't change physics but they acknowledged the fundamental area of concern others have not discussed.
