This Executive Order is valid provided that installation instructions for
this Power Flow Air Filter System will not recommend tuning the vehicle to

Changes made to the design or operating conditions of the Power Flow Air
Filter System as exempt by the ARB, which adversely affect the performance
of a vehicle‘s pollution control system shall invalidate this Executive

HKS USA, INC.                                      EXECUTIVE ORDER D—186—4
POWER FLOW AIR FILTER SYSTEM                       (Page 2 of 3)

Marketing of this Power Flow Air Filter System using any identification
other than that shown in this Executive Order or marketing of this Power
Flow Air Filter System for an application other than those listed in this
Executive Order shall be prohibited unless prior approval is obtained from
the ARB.  Exemption of the Power Flow Air Filter System 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 is granted based on a determination that the device
would not show an adverse effect in emissions if tested using the Cold—Start
CVS~75 Federal Test Procedure.   However,   the ARB finds that reasonable
grounds exist to believe that use of the Power Flow Air Filter System may
adversely affect emissions of motor vehicles when operating under conditions
outside the parameters of the previously prescribed test procedures.
Accordingly, the ARB reserves the right to conduct enission 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
Power Flow Air Filter 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effectively rescinded as of the date the test results are validated.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 Power Flow Air Filter System will affect the durability
of the emission control system, HKS USA, Inc. 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 durability.

In addition to the fctegoing, 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 Requlations section 2222 et seq.

This Executive Order does not constitute any opinion as to the effect the
use of this Power Flow Air Filter System may have on any warranty either
expressed or implied by the vehicle manufacturer.


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.

                  . HKS USA, INC.                                                                                                     EXECUTIVE ORDER D—186~4
                    POWER FLOW AIR FILTER SYSTEM                                                                                      (Page 3 of 3)

                    Viclation of any of the above conditions shall be grounds for revocation of
                    this order. The order may be revoked only after 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 the
                     hearing that grounds for revocation exist.

                     Executed at El uonte,§Cali£ornia, thilcjagi_ day of January,                                                                  1992.
