State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—747—2 Relating to Exemptions under Section 27156 of the Vehicle Code Trick Flow Specialties Throttle Bodies Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of the Vehicle Code (VC); and Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the Health and Safety Code and Executive Order G—14—012; IT IS ORDERED AND RESOLVED: That installation of the Throttle Bodies, manufactured by BBK Performance and marketed by Trick Flow Specialties, has been found not to reduce the effectiveness of the applicable vehicle pollution control systems, and therefore, the Throttle Bodies are exempt from the prohibitions in VC Section 27156 for installation on the following vehicle applications listed in Exhibit A. The Trick Flow Specialties Throttle Body is a new throttle body that has been designed to OEM specifications with a slightly larger diameter bore. A new throttle plate is included to match up with the new diameter bore. Installation is in the stock location, with no other modifications needed for proper installation. This Executive Order is valid provided that the installation instructions for the Throttle Bodies will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer. Changes made to the design or operating conditions of the Throttle Bodies, as exempt by the Air Resources Board, which adversely affect the performance of the vehicle‘s pollution control system shall invalidate this Executive Order. The Air Resources Board reserves the right in the future to review this Executive Order and the exemption provided herein to assure that the exempted add—on or modified part continues to meet the standards and procedures of Title 13, California Code of Regulations, Section 2222, et seq. This Executive Order is granted based on submitted emission test data generated in support of Executive Orders D—245—15 and D—245—17. Test results showed that emission levels, with the Throttle Bodies installed, met the applicable emission standards when tested using the Cold—Start CVS—75 Federal Test Procedure (FTP) test cycle and the Supplemental Federal Test Procedure (SFTP USO6) test cycle. Examination of the OBD II system showed that the Throttle Bodies did not affect OBD II system operation.

The Air Resources Board reserves the right in the future to review this Executive Order and the exemption provided herein to assure that the exempted add—on or modified part continues to meet the standards and procedures of Title 13, California Code of Regulations, Section 2222, et seq. THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF THE THROTTLE BODIES. Marketing of the Throttle Bodies using any identification other than that shown in this Executive Order or marketing of the Throttle Bodies for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board. No claim of any kind, such as "Approved by the Air Resources Board", may be made with respect to the action taken herein in any advertising or other oral or written communication. Violation of any of the above conditions shall be grounds for revocation of this order. The order may be revoked only after a ten—day written notice of intention to revoke the order, in which period the holder of the order may request in writing a hearing to contest the proposed revocation. If a hearing is requested, it shall be held within ten days of receipt of the request and the order may not be revoked until a determination is made after the hearing that grounds for revocation exist. Executed at El Monte, California, this 23 day of January 2017. Annette Hebert, Chief Emissions Compliance, Automotive Regulations and Science Division TRICK FLOW SPECIALTIES —THROTTLE BODIES—D—747—2
