The SEMA Garage is available to help SEMA member auto parts manufacturers develop products from start to finish. For many manufacturers, the process includes demonstrating that a vehicle will remain emissions-compliant when the product is installed. Emissions compliance is required for almost all performance and engine-related products, and the SEMA Garage is available to make the process as easy and affordable as possible.
Here are some basics about emissions compliance:
- Emissions compliance is a legal requirement. Both the state of California and the federal government have laws making it illegal for a company to sell performance products for street vehicles that could impact emissions. But products can comply with these laws by demonstrating that the product meets emissions compliance criteria. Two options are available; SEMA Certified-Emissions certifies that a product meets the EPA’s “reasonable basis” criteria making it legal for sale in 49-states, or obtaining a California Air Resources Board (CARB) Executive Order (EO) makes it legal in all 50 states.
- Emissions compliance applies to almost all performance and engine products. Generally, any product that affects airflow into or out of the engine, impacts the containment or delivery of fuel or affects the functionality of an emissions control system or device must demonstrate emissions compliance to be considered legal for street use. This includes, but is not limited to, intake systems, exhaust components, tuning products, intercoolers, turbos and superchargers.
- A common misconception is that as long as you don’t sell your product in California, it is 49-state legal. This is not the case. The Federal Clean Air Act prevents the modification of vehicles with products that impact emissions unless the product has demonstrated a reasonable basis for claiming emissions compliance. The EPA’s Tampering Policy provides guidance for such a demonstration, and SEMA Certified-Emissions is designed to provide documentation for assurance of 49-state legality.
- Both CARB and EPA oversee air quality and are authorized to administer fines against manufacturers, sellers, installers and users of products that do not comply with the clean air laws.
Emissions compliance should be considered a priority for manufacturers that make engine-related products that are intended for street use. SEMA is here to help. Our Compliance Center includes experts and resources available to help members navigate the process, including:
- Evaluation of your product and recommendations for compliance procedures
- Assistance with SEMA-Certified Emissions or the CARB EO process
- Interaction with CARB staff on your behalf

- The SEMA Garage in Diamond Bar, CA, includes an automotive emissions laboratory where SEMA manufacturer members are able to test their products at an affordable cost. Our testing capabilities include all tests* required for obtaining a SEMA-Certified Emissions certification or a CARB EO for both gasoline and diesel vehicles. *excluding evaporative emissions tests
