                                 EXECUTIVE ORDER D—453—2
                          Relating to Exemptions Under Section 27156
                                       of the Vehicle Code


                                      MOSS MOTORS
                                 MAZDA SUPERCHARGER KIT


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 39518 of
the Health and Safety Code and Executive Order G—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the Mazda Supercharger Kit,
manufactured by Jackson Racing 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 all 1990 to 2000 model year Mazda Miata vehicles powered by
a 4—cylinder engine.

Moss Motors‘ Mazda Supercharger Kit includes an Eaton supercharger designed to give a
maximum boost of 6 psi., a new fue! 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. The
following are the applicable pulley sizes:

Application                         Crank Pulley Dia.         Supercharger Dia.
1990—1993                               512"                       2.9"
1994—2000                               5.12"                      2.6"

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.

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.

This Executive Order shall not apply to any Mazda Supercharger Kit advertised, offered for
sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer to an
ultimate purchaser.

Mazda Supercharger Kit                                (Page 2 of 3)



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 prohibited unless prior approval is obtained from the Air Resources
Board. Exemption of the Mazda Supercharger Kit 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 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 emissions test data submitted by the
kit manufacturer:                                                                                 '

Test results showed that the Supercharger Kit when installed on the vehicles did not cause
tailpipe emissions to exceed the vehicle‘s applicable emission standard during a Cold Start
CVS—75 Federal Test Procedure. This Executive Order is also based on On Board Diagnostic
Il (OBD II) testing conducted on the a 1999 Mazda Miata and 1998 Honda Civic. Test data
showed that the Supercharger Kit when installed on the vehicles did not affect the vehicles‘
ability to perform OBD I! monitoring. The test data from the Honda Civic is being used to
further substantiate compliance for vehicles meeting the LEV emission standards. Based on
previous experience with these devices, the staff concludes that Mazda Miata applications
meeting LEV emission standards will exhibit similar emissions performance.

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/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.

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‘ MAZDA
SUPERCHARGER KIT.

order may be revoked only after a ten—day written notice of intention to revoke the order, in

revocation exist.

Executive Order D—453—1, dated March 1999, is superseded and of no further force and effect.
