*Cannot be sold in California

California law does allow marketing and sale of an aftermarket performance part after an evaluation by CARB to ensure the part does not raise emissions. Once CARB approves the part, it is granted an executive order that allows the sale and installation of the part on pollution-controlled vehicles. State law also requires manufacturers, retailers, and distributors to take steps to ensure that consumers understand the legality of parts offered for sale and to discourage illegal modifications to vehicles.
