I don't know about all the fitment stuff on that, as far as a smog in Ca it depends on the age and I think how many owners it has had, for age I think it is 7 years if you are the original owner, and maybe a 2nd owner and/or if it was sold within a certain time period, I think if I sold it now then it would require a smog. (not sure on the details) but I am the 2nd owner on my 2018 and it has not required a smog (yet) I have a CAI on mine that I had shipped from another person out of state because it is not carb complaint and I am not worried about it, when it comes time to get a smog I can just put the oem intake back on, go get it smogged and then put the CAI back on
