State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—578 Relating to Exemptions Under Section 27156 of the Vehicle Code Trans—Dapt Performance Products Throttle Body Spacers Pursuant to the authority vested in the Air Resources Board by Section 27156 of the Vehicle Code; and Pursuant to the authority vested in the undersigned by Section 39515 and Section 39516 of the Health and Safety Code and Executive Order G—45—9; IT IS ORDERED AND RESOLVED: That the installation of the throttle body spacers, as listed in Exhibit A, manufactured and marketed by Trans—Dapt Performance Products, 16410 Manning Way, Cerritos, California 90703 has been found not to reduce the effectiveness of the applicable vehicle pollution control system and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for the vehicle applications listed in Exhibit A. The throttle body spacers that are included in this Executive Order are the Torque Curve Spacer, Standard Spacer, Wide Open Spacer, and the Swirl Torque Spacer. Each spacer is designed for vehicles with either a multi—point or throttle body fuel injection system, and is installed under the throttle body. — This Executive Order is valid provided the installation instructions for the throttle body spacers will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer. This Executive Order shall not apply to any Trans—Dapt Performance Products‘ throttle body spacers advertised, offered for sale, sold with, or installed on a new motor vehicle prior to or concurrent with transfer to an ultimate purchaser. Changes made to the design or operating conditions of the throttle body spacers, as exempt by the Air Resources Board, which adversely affect the performance of the vehicle‘s pollution control system shall invalidate this Executive Order. Marketing of the throttle body spacers using any identification other than that shown in this Executive Order or marketing of the throttle body spacers for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board. Exemption of the throttle body spacers shall not be construed as exemption to sell, offer for sale, or advertise any component of the kit as an individual device. This Executive Order does not constitute any opinion as to the effect the use of the throttle body spacers may have on any warranty either expressed or implied by the vehicle manufacturer.

«2. This Executive Order is granted based on an engineering evaluation which determined that the throttle body spacers will have no adverse impact on exhaust emissions if tested in accordance with the Cold—Start CVS—75 Federal Test Procedure. Furthermore, On—Board Diagnostic II (OBD It) testing, using a 1998 model—year 4.0L Jeep Grand Cherokee, a 2003 model—year 4.6L Ford F—150, and a 2002 model—year 5.3L Chevrolet truck, showed that the throttle body spacers did not affect the vehicle‘s ability to perform its OBD II monitoring functions. The ARB 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 TRANS—DAPT PERFORMANCE PRODUCTS‘ THROTTLE BODY SPACERS. 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.
