CARB EO Testing

CARB Executive Order (EO) Testing

Certify your aftermarket parts for the Californian market

CARB Executive Order (EO) Testing

California Vehicle Code, section 27156 (VC27156) and the Federal Clean Air Act (CAA) prohibit vehicle modifications which increase motor vehicle emissions.

However, since most properly engineered parts do not increase emissions, the laws allow for exemptions for the installation of parts proven by their manufacturer and the California Air Resources Board (CARB) not to increase emissions. The process by which these exemptions are granted is via an Executive Order (EO). You must be granted an EO in order to legally sell aftermarket parts in the state of California.

We can acquire the necessary vehicles, perform modifications, conduct the required tests, and provide reports of the results to ultimately grant a CARB Executive Order.

You'll be on the fast-track to getting your aftermarket parts certified for California.
