                                 EXECUTIVE ORDER D—747—2

                                 Relating to Exemptions under
                              Section 27156 of the Vehicle Code

                                     Trick Flow Specialties
                                        Throttle Bodies

Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of the
Vehicle Code (VC); and

Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the
Health and Safety Code and Executive Order G—14—012;

IT IS ORDERED AND RESOLVED: That installation of the Throttle Bodies, manufactured
by BBK Performance and marketed by Trick Flow Specialties, has been found not to reduce
the effectiveness of the applicable vehicle pollution control systems, and therefore, the
Throttle Bodies are exempt from the prohibitions in VC Section 27156 for installation on the
following vehicle applications listed in Exhibit A.

The Trick Flow Specialties Throttle Body is a new throttle body that has been designed to
OEM specifications with a slightly larger diameter bore. A new throttle plate is included to
match up with the new diameter bore. Installation is in the stock location, with no other
modifications needed for proper installation.

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

Changes made to the design or operating conditions of the Throttle Bodies, as exempt by
the Air Resources Board, which adversely affect the performance of the vehicle‘s pollution
control system shall invalidate this Executive Order.

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 Title 13, California Code of
Regulations, Section 2222, et seq.

This Executive Order is granted based on submitted emission test data generated in
support of Executive Orders D—245—15 and D—245—17. Test results showed that emission
levels, with the Throttle Bodies installed, met the applicable emission standards when
tested using the Cold—Start CVS—75 Federal Test Procedure (FTP) test cycle and the
Supplemental Federal Test Procedure (SFTP USO6) test cycle. Examination of the
OBD II system showed that the Throttle Bodies did not affect OBD II system operation.


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 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 THE
THROTTLE BODIES.

Marketing of the Throttle Bodies using any identification other than that shown in this
Executive Order or marketing of the Throttle Bodies for an application other than those
listed in this Executive Order shall be prohibited unless prior approval is obtained from the
Air Resources Board.

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    23 day of January 2017.
