Motor vehicle emissions standards are intended to help achieve and maintain air quality goals that benefit human health and the environment. The U.S. Environmental Protection Agency, the California Air Resources Board, Environment Canada, and other regulatory agencies prohibit the operation of vehicles on public roads that violate applicable emissions standards. The alteration of certified production vehicles to modify, remove, or render inoperable emissions control hardware or software, known as "tampering" is prohibited by the U.S. Clean Air Act and other laws. Tampering with motor vehicles emissions control systems is punishable by substantial monetary penalties. Consumers are responsible for complying with laws prohibiting tampering, and for ensuring that modified vehicles are operated in a manner that complies with applicable laws.
In an effort to help consumers maintain compliance with emissions regulations, the product descriptions for many parts include emissions-related warnings and notices. This page summarizes the emissions-related information that you may see in this website/catalog.
Parts Intended for Competition Use Only
This website/catalog includes parts that are intended solely for competition vehicles that will only be driven on a track or an off-road course. Such parts are not designed to be installed on vehicles that will be driven on public roads. The product descriptions for such parts are accompanied by the following warning:
This part is designed and intended for competition use only. It should not be installed on a vehicle that is driven on public roads and highways. Installation of this art on a vehicle driven on public roads and highways is likely to violate U.S. and Canadian laws and regulations relating to motor vehicle emissions.
Consumers are strongly advised not to install parts accompanied by this warning on vehicles that will be driven on public roads.
Replacement Parts Intended for Specific Vehicle Applications
This website/catalog also includes parts that are intended only as replacement parts for use in certain vehicle applications. The product descriptions for such parts are accompanied by the following notice:
This part is intended as a replacement part for use only in the application(s) identified in the product description. Installation of this part in a vehicle for which it is not intended may violate U.S. and Canadian laws and regulations related to motor vehicle emissions.
Consumers are strongly advised to install parts accompanied by this warning only in the vehicle applications for which they are intended.
Parts That Have Received a California Executive Order
The product descriptions for some parts in this website/catalog are accompanied by the (Fifty States Street Legal) icon and the following notice:
The “Fifty States Street Legal” icon means that this part has been determined by the California Air Resources Board (CARB) not to have an adverse effect on emissions when installed and used properly in the application(s) identified in the product description. Under EPA and CARB policy, such parts may be installed in vehicles driven on public roads and highways.
These add-on or modified parts are considered “Street Legal” because they have an Executive Order from the California Air Resources Board (CARB). Ford Performance has demonstrated through emission testing that the use of these parts does not adversely affect vehicle emissions of specified production vehicles with certified emission control systems.
Parts accompanied by this logo and notice may be installed in the application(s) identified in the product description, and such vehicles may be driven on public roads. Consumers are advised to make sure that such parts are installed and used properly in order to maintain compliance with emissions standards.
Parts that are not accompanied by any of the above notices are judged by Ford to be unlikely to affect motor vehicle emissions in most vehicle applications, when properly installed and used. Consumers are responsible, however, for determining whether the installation of a component will affect the emissions of their particular vehicle.
