I'm having difficulty initiating the California smog check for my 2007 350Z with Nismo cold air intakes. I just move to Escondido from Connecticut, where the dual cold air intake was installed by the dealer. Upon attempting to have the car emission tested in Escondido today, I was informed that the intakes lacked a sticker certifying that the intakes were okay for California use. I would rather not put the original parts back on. Does any one know what to do about this problem or what the number should be on the sticker?

 

The emission testing place was referring to a CARB (California Air Research Board) sticker which certifies the intakes are emissions legal in California. Unfortunately, California is a b*tch to pass emissions and unfortunately, the Nismo intakes are not CARB legal. There are other intakes that are CARB legal.

 

Your reply was exactly on target. I will have to reinstall the original intakes.
Thanks again,

 

Or just goto one of the smog places that will give you the certificate so you can keep your nismo intake. PM kday.

 

I dont see why you wouldnt pass a smog test if you have done nothing on the exhaust end of you car. I think if you run the test as is you should be fine especially with Nismo which is a factory intake. If its a matter of the shop not wanting to do it, try another place that will lol. I am sure you can find one easily if not pm me and ill send you to this place in burbank that always works with any car and any issue to pass it.

 

An exhaust, especially from the cat back should have no effect on a smog as it doesn't actually change afr or any emissions. Certain intakes I believe will. I could be wrong.

 

Its an R tune part, not CARB legal. Put your stock intakes back on.

 

The borla td exhaust is carb legal from what I understand, but when installing I do not recall seeing a sticker. Should I be concerned about that? Sorry for thread jacking :/
