I‘m planning on moving to California soon, and I want to get a cold air intake system in my 2011 v6 Mustang coupe, until I saw that they were illegal in Cali. Why is that?
If would not be illegal if the manufacturer passes CARB standard and provide a sticker to say so. To answer your question, some cars have their pvc system connected to the air filter box. If the CAI does not have this connection then it is missing an emission system thus does not pass.

They're not illegal, they just need to meet certain specifications. See the link below for a more detailed explanation of what is required.
