    i figured it out from another thread...... the 63 model is the same as the 57 model but just before the 57 gets carb approved

    I know that Calif is one of the State's in which the 63-Model is Not Street Legal......I would check with K&N on the other State's where the 63-Model is Not Street Legal.

    Edit: Below is from K&N's Web Site...On the 63-3058 CAI.....This intake system is not legal for street use,
    in the following states:

    Arizona, California, Connecticut, District of Columbia, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington

    This intake system is legal for street use in most states. However, it is not legal for street use in California and the above states that have adopted California Emissions Standards under Section 177 of the Federal Clean Air Act of 1970. Intake systems are subject to governmental regulation in California and certain other states adopting the emission standards of the California Air Resources Board. In order for an intake system to be legal on a specific vehicle in California and the other adopting states, the part number must receive a CARB Executive Order (EO) number. This number makes the part legal for use only on specific years, makes and models of vehicles. A decal with CARB EO number for these parts must be displayed in the engine bay to satisfy smog inspection requirements.

    All K&N 57 series intakes for North American vehicles have received CARB EO numbers and are street legal in all 50 states.

    Some intake systems we sell beginning with the prefixes 63-, 69-, 77, & RK- are not legal for use in California and other states adopting CARB emission standards. Please check our website for the specific CARB status of each intake system we sell for a specific vehicle.
