                                        EXECUTIVE ORDER D—471—1
                                 Relating to Exemptions Under Section 27156
                                              of the Vehicle Code


                                       GRANATELLI MOTORSPORTS
                                           Mass Airflow Sensor



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 Mass Airflow Sensor, manufactured and
marketed by Granatelli Motorsports, 5469 Oakdale Avenue, Woodland Hills, California 91364 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 following Ford Motor Company vehicles listed in
Exhibit A of the Executive Order.

The Mass Air Flow Sensor is designed with two main parts: the sensor body and the electronics. The body is
manufactured out of a one piece metal casting, it contains the inlet tube, the sensor mounting, and an outlet
tube. The electronics are manufactured by the Ford Motor Company to be a stock replacement. The sensor fits
in the stock location with no modifications to the vehicle‘s electrical system or intake air system.

This Executive Order shall not apply to any Granatelli Motorsports Mass Airflow Sensor advertised, offered for
sale, or sold with or installed on, a motor vehicle prior to orconcurrent with transfer to an ultimate purchaser.

This Executive Order is valid provided that the installation instructions for the Mass Airflow Sensor will not
recommend tuning the vehicle to specifications different from those of the Ford Motor Company.

Changes made to the design or operating conditions of the Mass Airflow Sensor, 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 Mass Airflow Sensor using any identification other than that shown in this Executive Order or
marketing of the Mass Airflow Sensor 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 Mass Airflow
Sensor 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 an engineering evaluation and an On Board Diagnostic II (OBD II)
testing conducted on a 1999 Ford 4.6L truck, certified to a Low Emission Vehicle standard. Test data showed
that the Mass Airflow Sensor when installed on the vehicle did not affect the vehicle‘s ability to perform its
OBD II monitoring.                                                                                        *


Granatelli Motorsports                                                     Executive Order D—471—1
Mass Airflow Sensor                                                        (Page 2 of 2)




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

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 GRANATELLI MOTORSPORTS‘S MASS AIRFLOW SENSOR.

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.

Executed at El Monte, California, this
                                           !fl 16day of April 1999.
