You know the enforcement mechanism for that is pretty weak right? This only affects legit parts retailers like Rockauto, Autozone, Oreillys etc. Anyone that's not an actual vendor, like an individual, or vendors on ebay aren't affected by this due to lack of enforcement. The only way to get caught, is if someone goes out of their way and snitches on you.if you get caught, that friend is liable for the fines and legality of selling an illegal part to someone in CA. is it really worth it?
