Then there would need to be a catch-all law that says that. If there is no law making something illegal, they have no basis to ticket/fine you on. It has to be explicity stated that it's illegal or it will be pretty easy to get that **** thrown out in court.It's California, conversely to how the rest of the USA runs, it's illegal unless there is a law explicitly stating it's legal. IF two laws seem to conflict, whichever one makes CA more money, wins.
I did another search, and I can only find documents from a couple years back saying intercoolers for gas engines are exempt. I'm not finding anything more current that has any additional information though. I posted the original link a few posts back.
