                               EXECUTIVE ORDER D—446
                     Relating to Exemptions Under Section 27156
                                 of the Vehicle Code

                                   KNIGHT ENGINEERING
                               ICEMAN COOL AIR SYSTEM

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 Iceman Cool Air
System, manufactured and marketed by Knight Engineering, 45322 North Trevor
Avenue, Lancaster,    California    93534 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 Acura,    Honda, Mitsubishi,   American Motors,   and Saturn vehicles
listed in Exhibit A.

The Iceman Cool Air System includes the following main components:  open—
element cotton gauze reusable air filter, intake system tubing, assorted
brackets,    and hardware.

This Executive Order is valid provided that the installation instructions for
the Iceman Cool Air 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 Iceman Cool Air
System, 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 Iceman Cool Air System using any identification other than
that shown in this Executive Order or marketing of the Iceman Cool Air System
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 Iceman Cool Air System shall not be construed as exemption to
sell, offer for sale, or advertise any component of the kit as an individual

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

ICEMAN COOL AIR SYSTEM                                             (Page 2 of 3)

This Executive Order is granted based on emissions testing and examination of
the On—Board Diagnostic II (OBD—II) system of the vehicle in the modified
configuration.  The emissions results, with the original equipment
manufacturer‘s    (GM‘s)   deterioration factors applied,           are shown below:

                 Emission Level     0.070       3.0        0 .6       0.000766

The test results for the Knight Engineering Iceman Cool Air System meet 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 Knight Engineering Iceman
Cool Air 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 Knight Engineering Iceman Cool Air 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 Iceman Cool Air
System will affect the durability of the emission control system, Knight
Engineering 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 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 Requlations, 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.                            fl4
