What year is the car if its 2002 and later no smog for a couple of years. I have had a 95 civic pass here in California with a intake on it. I guess its all in the mechanic you choose. Its only a visual inspection here in Cali. It has nothing to do with the emissions count. They even check the pressure for the gas cap here. I had to buy a new one because it couldnt keep the pressure regulated.
