California Air Resources Board acts to streamline aftermarket parts exemption process
For immediate release
SACRAMENTO – Today, the California Air Resources Board adopted an updated and streamlined approach to the current procedures for exemptions from California anti- tampering laws for add-on and modified “aftermarket” parts.
This approach was developed in response to rapidly evolving vehicle technology. CARB worked cooperatively with the aftermarket parts industry to update its regulations to address today’s advanced vehicle technology while still protecting the integrity of the systems that controls harmful and toxic emissions.
”These new requirements address recent and more advanced technologies that didn’t exist when the procedures were first written,” said CARB Assistant Executive Officer Annette Hebert. “This is a positive outcome that will benefit consumers and industry and result in faster access to approved aftermarket parts.”
Aftermarket parts are modifications that were not part of the design of the vehicle or engine when originally certified for sale in California. Any parts that have the potential to impact emissions are subject to the protections of California’s anti-tampering regulation, and require an exemption from CARB prior to being sold in the state.
Aftermarket parts are typically installed by consumers to improve performance, add functions, or for aesthetic value. Permission to install parts such as superchargers, turbos, air intakes, and exhaust systems is given only after a thorough engineering evaluation and testing demonstrates that the parts will not impact the performance of the vehicle’s emissions controls.
Over 200 applications for aftermarket parts are submitted annually and that number is expected to grow in the coming years. Since the last amendments to the aftermarket process in 1990, there have been revolutionary changes in the design of new vehicles and emission control systems. CARB staff recognized the rapid advancements in engine and drive train engineering and made updating its evaluation and review process of aftermarket parts a priority.
The improvements adopted today will clarify exemption requirements by presenting a more detailed description of CARB review criteria and providing uniform information to manufacturers regarding testing requirements. The streamlined application and review process will allow products to get to the market faster. The new process will commence in 2021.
