Hi All, I am considering either a cold air intake (CAI) or JWT pop charger for my 2006 Enthusiast Coupe. My first question is: Is a CAI smog legal in CA or why wouldn't it be? I think my car is too new, so AEM and Injen hasn't updated their info on this yet. I'm also reading that legality is pending on some CAI in CA. JWT pop charger seems like the easiest and cheapest way to do intake, but how does it compare to metal piping in a CAI? In my experience with intakes, the metal intake pipes make a big difference in the sound and sound great, but I am hearing that people are also happy with the sound on JWT with the stock plastic piping?
