K&N Intake Kits, Are They Street Legal?
Every kit we sell is street legal in most states. California and other states that have adopted California emission standards require an intake system to be inspected by the California Air Resources Board (CARB). If the system meets the regulatory requirements, CARB will issue an Executive Order (EO) number. This number, when referenced, will inform a smog inspector that the intake system does not cause the vehicle to be in violation of state emissions standards. EO numbers are assigned for a specific part number on a specific vehicle. When a new year of the vehicle is released, a resubmission to CARB is required. The time required to go through the regulatory process can be lengthy and there is no guarantee the system will be found acceptable for each successive vehicle model year.
With the exception of our 57i Series, our intake systems intended for street use are submitted to CARB for each model year. Intakes with EO numbers means the product meets CARB emission standards ONLY for the vehicle model years cited. Generally, the EO will not cover current year vehicles due to the lengthy regulatory review process. If a model year is not cited on the EO, the part is not legal for sale or use for that specific model year in California and other states that have adopted California emission standards.
To determine if an intake kit is CARB exempt for the applications listed, view the applications tab on the product page to view if the product is legal in your state. A notice will open indicating the CARB exemption status for the intake.States that have adopted California emission standards include: Arizona, California, Connecticut, District of Columbia, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington.
