How can I tell if a part will pass emmisions?

Kamaro Killer · 09-06-2002, 05:48 PM

Because California has such strict emmision laws I know there are a lot of parts I can't use. I was wondering if there is any way of knowing whether the part can be used in a combo, and still pass smog. I know there is a CARB number (California Air Resource Board) or something like that that is on a part, but some don't have CARB numbers on them. There's a thread going that asks if GT40P's will pass Cali's emmision test. Instead of asking about each head, intake, cam, headers, is there some website or somewhere I could research this? Thanks, Keith

You need to contact the part manufacturer, and ask them if your specific part has a CARB EO number.

Take care,

gt-40 and gt-40 p's are O-E heads no problems with emmisions if the visual inspector even would notice the diffrence. as for parts chris was right aboput the manufacture to see if there is an exemtion # if the inspector gives you grief. we dont have air care here but in BC they do the sniffer test and when i was there i had to have a tire changed and the mech put my car on the sniffer to tell me how lucky i was to not have to pass and to his suprise my car was within the allowable margin. but i would of failed if he had done a visuale to back it up . diffrent places diffrent laws.
