Do AirSensors EFI systems have a CARB number, that is, qualify for exemption under Section 27156 of CARB (California Air Resources Board) Vehicle Code?
The AirSensors Analog system with Model N-8A-HD ECU has received Executive Order D-163 (click to view pdf file) for installation on ’86 and older GM 454 CID heavy-duty gasoline engines. No other AirSensors system has been exempted by CARB that we know of. Installation of AirSensors systems in any vehicle must comply with applicable State and Federal regulations in force at the time of the vehicle’s manufacture and retain any emissions control devices installed by the manufacturer. Vehicles classified as “off road” may be governed by separate regulations. Consult with your State Motor Vehicles Department about local laws.
