                                EXECUTIVE ORDER D—176—41

                          Relating to Exemptions Under Section 27156
                                    of the California Vehicle Code

                                    Dinan Engineering, Inc.
                                   High Flow Throttle Bodies

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—14—012;

IT IS ORDERED AND RESOLVED: That the installation of the High Flow Throttle
Bodies, manufactured and marketed by Dinan Engineering, Inc. of 865 Jarvis Drive,
Morgan Hill, California 95037, has been found not to reduce the effectiveness of the
applicable vehicle pollution control systems and, therefore, is exempt from the
prohibitions of Section 27156 of the Vehicle Code for the following vehicle applications
as listed in Exhibit A.

The High Flow Throttle Body includes a modified throttle body with a larger diameter for
increased air flow. No other modifications are required for installation other than the
replacement of the stock unit with Dinan‘s unit.

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

Changes made to the design or operating conditions of the High Flow 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.

Marketing of the High Flow Throttle Bodies using any identification other than that shown
in this Executive Order or marketing of the High Flow 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.

This Executive Order does not constitute any opinion as to the effect the use of the
High Flow Throttle Bodies may have on any warranty either expressed or implied by the
vehicle manufacturer.

This Executive Order is granted based on previously submitted emission test data
generated on a 2006 model year BMW 325i, engine test group GBMXVO3.O0N52, certified
to the Low Emission Vehicle II Ultra Low Emission Vehicle (LEV II ULEV) emission
standards. Test results on the BMW 325i showed that emission levels, with Dinan
Engineering, Inc.‘s High Flow Throttle Body installed, met the applicable emission


                                            3.


standards when tested using the Cold—Start CVS—75 Federal Test Procedure (FTP) and
the Supplemental Federal Test Procedure (SFTP USO6) test cycles. Examination of the
OBD II system showed the High Flow Throttle Body did not affect OBD II system
operation. Results from emission testing conducted at Automotive Testing and
Development Services, Inc., located in Ontario, California are listed below with
deterioration factors applied.

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 HIGH FLOW
THROTTLE BODIES.

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.
