If you would like to know which aftermarket parts are legal, check out the (EO) database on the California Gov website.

If you have some time on your hands, you can do a search by "listing the executive orders by device".
It's a huge list so you'll have to keyword which manufacturer your looking for. Just cross reference the part number that your inquiring. Hope this helps.
