                                EXECUTIVE ORDER D—458—1
                       Relating to Exemptions Under Section 27156
                                    of the Vehicle Code

                                   DJ MOTORSPORTS
                                HIGH—FLOW INTAKE DUCT

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 High—Flow Intake Duct,
manufactured and marketed by DJ Motorsports, 23091 Antonio Parkway, Unit 335,
Rancho Santa Margarita, California 92688, 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 Ford and GM
vehicles listed in Exhibit A.

The High—Flow Intake Duct includes the following main components: open-elemént
reusable air filter, intake system tubing, assorted brackets, and hardware.

This Executive Order is valid provided that the installation instructions for the High—Flow
Intake Duct will not recommend tuning the vehicle to specifications different from those
of the vehicie manufacturer.

Changes made to the design or operating conditions of the High—Flow Intake Duct, as
exempt by the Air Resources Board, which adversely affect the performance of the
vehicle‘s pollution control system shall invalidate this Executive Order.

This Executive Order shall not apply to any High—Flow Intake Duct advertised, offered
for sale, sold with, or installed on, a motor vehicle prior to or concurrent with transfer to
an ultimate purchaser.

Marketing of the High—Flow Intake Duct using any identification other than that shown in
this Executive Order or marketing of the High—Flow Intake Duct for an application other
than those listed in this Executive Order shall be prohibited unless prior approval is
obtained from the Air Resources Board.


    DJ MOTORSPORTS                                             EXECUTIVE ORDER D—458—1
    HIGH—FLOW INTAKE DUCT                                :            (Page 2 of 3)

    This Executive Order does not constitute any opinion as to the effect the use of the
    High—Flow Intake Duct may have on any warranty either expressed or implied by the
    vehicle manufacturer.

    This Executive Order is granted based on an examination of the On—Board Diagnostic II
    (OQBD—11) system of the vehicle in the modified configuration, and an engineering
    evaluation of the emissions impact of the device if measured using the Cold—Start CVS—
    75 Federal Test Procedure. However, the ARB finds that reasonable grounds exist to
    believe that use of the DJ Motorsports High—Flow Intake Duct systems may adversely
    affect emissions of motor vehicles when operating under conditions outside the              ,
    parameters of the CVS—75 Federal Test Procedure. Accordingly, the ARB reserves the
    right to conduct additional emission tests, in the future, as such tests are developed,
    that will more adequately measure emissions from all cycle phases. If such test results
    demonstrate that the DJ Motorsports High—Flow Intake Duct adversely affect emissions
    during off—cycle conditions (defined as those conditions which are beyond the
    parameters of the Cold—Start CVS—75 Federal Test Procedure), this Executive Order
    shall be effectively rescinded as of the date the test results are validated. Further, if
    such test results or other evidence provides the ARB with reason to suspect that the
    High—Flow Intake Duct will affect the durability of emission control systems, DJ
    Motorsports shall be required to submit durability data to show that the durability of
    vehicle emission control systems are not, in fact, affected and/or that the add—on or
    modified part demonstrates adequate durability.

    In addition to the foregoing, 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.


    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

     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 after
     hearing that grounds for revocation exist.

     Executed at El Monte, California, this (23 day of August 2000.
