                              EXECUTIVE ORDER D-369-12

                              Relating to Exemptions under ,
                            Section 27156 of the Vehicle Code

                       Ford Twisted Wedge Street Cylinder Heads

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 Sections 39515 and 39516 of the
Health and Safety Code and Executive Order G-02-003;

IT IS ORDERED AND RESOLVED: That installation of the Ford Twisted Wedge Street
Cylinder Heads, manufactured by Trick Flow Specialties of 285 West Ave., Tallmadge,
OH 44278, has been found not to reduce the effectiveness of the applicable vehicle
pollution control systems, and therefore, the Twisted Wedge Street Cylinder Heads are
exempt from the prohibitions in Section 27156 of the Vehicle Code for installation on the
vehicles listed in Attachment A.

This Executive Order is based on previously submitted emissions test data conducted
by Trick Flow Specialties on a 1996 Ford Bronco with a 5.8L engine. Test results
showed that exhaust emissions with Twisted Wedge cylinder heads installed on the
vehicle met the vehicle's applicable emission standard during a Cold-Start CVS-75
Federal Test Procedure and On-Board Diagnostic II System tests.

If evidence provides the Air Resources Board with reasons to suspect that the Twisted
Wedge Street Cylinder Heads will affect the durability of the emission control system,
Trick Flow Specialties shall be required to submit durability data to show that the
durability of the vehicle emission control system is not, in fact, affected andlor that the
add-on or modified parts demonstrate adequate durability.

This Executive Order is valid provided that installation instructions for the Twisted
Wedge Street Cylinder Heads do not recommend tuning the vehicles to specifications
different from those of the vehicle manufacturer.

Changes made to the design or operating conditions of the Twisted Wedge Street
Cylinder Heads, as exempt by the Air Resources Board, which adversely affect the
performance of the vehicles' emission control system, shall invalidate this Executive
Order.


Marketing of the Twisted Wedge Street Cylinder Heads using identification other than
that shown in this Executive Order or for an application other than that listed in this
Executive Order shall be prohibited unless prior approval is obtained from the Air
Resources Board. Exemption of the Twisted Wedge Street Cylinder Heads shall not be
construed as exemption to sell, offer for sale, or advertise any component of the system
as an individual device.

This Executive Order shall not apply to any Twisted Wedge Street Cylinder Heads
advertised, offered for sale, sold with, or installed on a motor vehicle prior to or
concurrent with transfer to an ultimate purchaser.

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

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.

In addition to the foregoing, the Air Resources Board 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
California Code of Regulations, Title 13, 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 TRICK FLOW
SPECIALTIES' CYLINDER HEADS.

Violation of any of the above conditions shall be grounds for revocation of this Executive
Order. The Executive Order may be revoked only after a ten day written notice of
intention to revoke the Executive Order, in which period the holder of the Executive
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 Executive
Order may not be revoked until a determination is ???adeafter the hearing that grounds
for revocation exist.

Executed at El Monte, California, this    24       day of August 2009.
