        California 92618 has been found not to reduce the effectiveness of the

        open—element reusable air filter, intake system tubing, assorted brackets, and

        This Executive Order is valid provided that the installation instructions for
        the Air Intake System 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 Air Intake System,
        as exempt by the Air Resources Board, which adversely affect the performance
        of the vehicle‘s pollution control system shall invalidate this Executive

        Marketing of the Air Intake System using any identification other than that

 J MOTORSPORTS                          .                      EXECUTIVE ORDER D—458
ALIR INTAKE SYSTEM                                              (Page 2 of 2)

This Executive Order is granted based on engineering evaluation of the impact
of the Air Intake System on exhaust and evaporative emissions,                  as well as an
examination of the On—Board Diagnostic II          (OBD—II})   system of the vehicle in
the modified configuration.

It has been determined that the DJ Motorsports Air Intake System meets the
criteria for exempting general criteria parts as specified in the "Procedures
for Exemption of Add—On and Modified Parts".  However, the ARB finds that
reasonable grounds exist to believe that use of the DJ Motorsports Air Intake
System 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 Air Intake System adversely affects 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effectively rescinded as of the date the test results are validated.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 Air Intake System will affect the durability of the emission control
system,   DJ Motorsports shall be required to submit durability data to show
that the durability of the vehicle emission control system is not, in fact,
affected and/or that the add—on or modified part demonstrates adequate

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 Reqgulations,             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 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 after hearing that grounds
for revocation exist.                       7QQ

Executed at El Monte,   California,   this        (é;    a      September 1998.
