I've already felt a nudge on this...
Took my truck to get smog checked 2 weeks ago, DING Fail without ever being hooked up.
My Volant Cold Air Intake didn't have the 50 State ARB sticker on it anymore....you could see where it has been for the last 18 years...
Guy said sorry, that intake wont pass....Googled it and sure enough, its not even legal anymore nor can I get that sticker from the MFG.
Eff this, I'll be back Smog guy...
Come back with the stock intake set up and air filter....guy says "I'm just letting you know, if that is not your Air Intake, ECU or etc....you won't be able to switch it later.
The new system logged the serial numbers of my stuff, each year moving forward it will compare if there have been any changes. It was all my OEM stuff, so no problem there.
Yup, CARB is in full effect on this stuff now. Tossed the Volant system in the trash and now enjoy a much nicer quieter driving experience....LOL.
I'm so over anything not OEM these days.
