Okay, so i'm pretty much a noob here to the new turbo's and 4 cylinder engines and mods in general. So i was reading over the web that Cold Air Intakes are actually illegal in california because of smog and emission restrictions. Now, heres the thing, I'm going for the Airaid CAI or A JLT, i want to know if anyone has had any problems using CAIs in Cali or any issues with law enforcement in that matter. Any response would be great. Much thanks, this forum has been such a big help so far!
