                                      EXECUTIVE ORDER D—453
                               Relating to Exemptions Under Section 27156
                                            of the Vehicle Code

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 6 PSI. Mazda Supercharger Kit,
manufactured and marketed by Moss Motors, 400 Rutherford Avenue, Goleta, California 93117 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 1990—98 Mazda vehicles powered
by a 1.5 to 2.6 liter 4 cylinder engine, excluding any vehicle certified to a low emission vehicle standard.

The following engine families are certified to a low emission vehicle standard and are excluded from
this exemption: 1996, TTK1.SVJG2EK, TTKIL.6VJG2EK, and TTK2.0VJG2EK, 1997, VTKI.SVJG2EK
VTK2.OVJG2EK 1998, WTKXVO1.5VDM.

Moss Motors Mazda Supercharger Kit includes an Eaton supercharger designed to give a maximum
boost of 6 psi., a 2.8" diameter pulley for the supercharger, a 5.0" diameter auxiliary crankshaft pulley, a
new fuel pressure regulator and an aftermarket open element air cleaner to replace the original equipment
air cleaner.

Modifications to the emissions control system include a relocation of the throttle body, and a 4 degree
retard in ignition timing.

This Executive Order is valid provided that the installation instructions for the supercharger will not
recommend tuning the vehicle to specifications different from those submitted by Moss Motors. Moss
Motors recommends that only 92 octane fuel be used and ignition timing be set at 6 degrees BTDC.

Changes made to the design or operating conditions of the supercharger, 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 supercharger using any identification other than that shown in this Executive Order or
marketing of the supercharger for an application other than those listed in this Executive Order shall be

Mazda Supercharger Kit                                         (Page 2 of 3)




prohibited unless prior approval is obtained from the Air Resources Board. Exemption of the MOSS
supercharger shall not be construed as exemption to sell, offer for sale, or advertise any component ofthe
kit as an individual device.

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

This Executive Order is granted based on the following submitted emissions test data on a 1994 Mazda
Miata:
                     NMHC CO            NOX
Standards            0.25      3.4      0.4
W/ device            0.12      1.3      0.3

Test results showed that the Mazda Supercharger Kit when installed on the vehicle did not cause tailpipe
emissions to exceed the vehicle‘s applicable emission standard during a Cold Start CVS—75 Federal Test
Procedure. This Executive Orderis also based on On Board Diagnostic II (OBD II) testing conducted on a _
1997 Mazda Miata. Test data showed that the Mazda Supercharger Kit when installed on the vehicle did
not affect the vehicle‘s ability to perform its OBD II monitoring:

However, the ARB finds that reasonable grounds exist to believe that use of the Mazda Supercharger Kit
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
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 Mazda Supercharger Kit
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 Mazda Supercharger Kit will affect the durability of the
emission control system, Moss Motors shall be required to submit durability data to show that the
durability of the vehicle emission control system is not, in fact, affected and/orthat 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.

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 MOSS MOTORS‘ SUPERCHARGER.

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.

Executive Order D—341—1, dated March, 1996, granted to Garrett Performance Products is superseded and
of no further force and effect.
