Cyclone Device Exemption.pdf

The California Air Resources Board (ARB) issued Executive Order D-267, exempting the KID Cyclone device from the prohibitions of Section 27156 of the Vehicle Code. The device, designed for installation on specific vehicles, is a cylindrical component with six blades that increases turbulence in the air intake passage. An engineering evaluation found that the device would not have significant adverse effects on emissions if tested according to the Cold-Start CVS-75 Federal Test Procedure. The ARB staff recommends granting KID an exemption, and Executive Order D-267 was issued. The order is valid provided that installation instructions do not recommend tuning the vehicle to different specifications, and changes to the device's design or operating conditions that affect the vehicle's pollution control system will invalidate the order. The ARB reserves the right to review and revoke the exemption if the device no longer meets standards and procedures.

Key conditions and limitations include:
- The device must be installed according to the manufacturer's instructions.
- The device must not be marketed using a different identification or for applications other than those listed.
- The ARB may revoke the order if the device's design or operating conditions are changed in a way that affects the vehicle's pollution control system.
- The order does not constitute an endorsement or certification of the device by the ARB.
- The manufacturer may not claim that the device is "approved" by the ARB in any advertising or communication.

The evaluation of the KID Cyclone device was conducted in accordance with Section 2222 of the California Code of Regulations, Title 13. The device was tested using the CVS-75 FTP test procedure, and the results showed no significant increase in emissions. The ARB staff concluded that the installation of the KID Cyclone device would not adversely affect exhaust emissions from vehicles for which an exemption is requested.
