                                  EXECUTIVE ORDER D—623

                         Relating to Exemptions Under Section 27156
                                      of the Vehicle Code

                                        T&T Motorsports
                                     Throttle Body Spacers

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 Throttle Body Spacers,
manufactured and marketed by T&T Motorsports, 11800 Sleeman Gulch Road, Lolo, Montana
59847 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 vehicle applications listed in Exhibit A.

The Throttle Body Spacer is a one inch thick spacer installed between the throttle body and
the intake manifold. A helix curve is machined into the openings of the throttle body spacer.

This Executive Order is valid provided the installation instructions for the Throttle Body
Spacers will not recommend tuning the vehicle to specifications different from those of the
vehicle manufacturer.

This Executive Order shall not apply to any T&T Motorsports‘ Throttle Body Spacers
advertised, offered for sale, sold with, or installed on a new motor vehicle prior to or concurrent
with transfer to an ultimate purchaser.

Changes made to the design or operating conditions of the Throttle Body Spacers, 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 Throttle Body Spacers using any identification other than that shown in this
Executive Order or marketing of the Throttle Body Spacers 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 Throttle Body Spacers 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 Throttle
Body Spacers may have on any warranty either expressed or implied by the vehicle
manufacturer.

This Executive Order is granted based on an engineering evaluation which determined that the
Throttle Body Spacers will have no adverse impact on exhaust emissions if tested in
accordance with the Cold—Start CVS—75 Federal Test Procedure. Furthermore, On—Board
Diagnostic II (OBD II) testing, using a 2005 model—year 4.7L Dodge Dakota, a 1997
model—year 5.7L Chevrolet Truck, and a 2006 model—year 3.0L Ford 500, showed that the
Throttle Body Spacers did not affect the vehicle‘s ability to perform its OBD II monitoring
functions.


                                               27—


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 T&T MOTORSPORTS‘
THROTTLE BODY SPACERS.

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 is made after the hearing that grounds
for revocation exist.

Executed at El Monte, California, this   [ é"&dfay of October 2007.
