                                EXECUTIVE ORDER D—176—23

                         Relating to Exemptions Under Section 27156
                                      of the Vehicle Code

                                    DINAN ENGINEERING
                                     Supercharger System


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—02—003;

IT IS ORDERED AND RESOLVED: That the installation of the Supercharger System,
manufactured and marketed by Dinan Engineering, Inc., 865 Jarvis Drive, Morgan Hill, California
95037 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
installation on the following BMW vehicle applications:

                                                     Pulley Dia.     Supercharger            Max.
Model         Model Years     Engine Size     Crankshaft/Supercharger Drive Ratio            Boost
540i, 540iT   1996 to 1998       4.AL               5.5"/3.32"           1.68                8 psi.
540i, 540iT   1999 to 2003       4.AL               4.89"/3.48"          1.41                6 psi.

740i, 740iL   1999 to 2002       4.AL               4.89"/3.48"          1.41                6 psi.
   X5         2000 to 2002       4.AL               4.89"/3.48"          1.41                6 psi.
   X6         2002 to 2003       4.6L               4.89"/3.48"          1.41                6 psi.

The Supercharger System includes a Vortech V—25 supercharger, high flow injectors to replace the
stock injectors, a new ECU calibration, Turbotronics 9 (air flow meter bridge circuit), a fuel pressure
regulator, inlet and discharge supercharger tubes, and an open element K&N—type air filter.        The
supercharger kit does not utilize an air bypass valve.

The crankcase vent hose is relocated to the supercharger inlet pipe between the airflow meter and
the supercharger. The stock PCV valve is removed from the intake manifold and a new OEM PCV
valve is installed in the crankcase vent hose at the supercharger inlet pipe.    For 540i and X5
models, the Supercharger System includes a high volume fuel pump. For 1999 to 2003 540i and
740 models and 2000 to 2003 X5 models, a larger diameter air flow meter housing and intake
manifold are included with the kit. The air flow control valve is relocated 12 inches away from the
original location, and a check valve is added in the evaporative canister purge line to protect the
canister from boost pressure. For 1999 to 2003 740 models and 2000 to 2003 X5 models, an air
filter is added to the air pump inlet. The intake air temperature sensor is relocated from the air box
to the intake manifold for 1996 to 1998 540i and 740 models, only.


                                               sJs


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

This Executive Order shall not apply to any Dinan Engineering, Inc. Supercharger System
advertised, offered for sale, or sold with or installed on a motor vehicle prior to or concurrent
with transfer to an ultimate purchaser.

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

This Executive Order is granted based on the following submitted emissions test data on a
2000 model—year BMW 540i certified to the low—emission vehicle (LEV) emission standards.
Testing consisted of one Cold Start CVS—75 Federal Test Procedure with the Supercharger
System installed. The vehicle in the modified configuration met the applicable emission
standards, in grams per mile with deterioration factors applied:

       s           NMOG CO         NOx     HCHO
Standard           0.075 34        0.2     0.015
Device w/dfs       0.058 0.6       0.1     0.001

This Executive Order is also based on the On Board Diagnostic II (OBD 11) testing conducted
on the same vehicle. Test data showed that the Supercharger System when installed on the
vehicle did not affect the vehicle‘s ability to perform its OBD II monitoring.

The ARB finds that reasonable grounds exist to believe that use of the Supercharger System
may adversely affect emissions of motor vehicles when operating under conditions outside
the parameters of the previously prescribed test procedures. Accordingly, the ARB reserves
the right to conduct additional emission tests, in the future, as such tests are developed, that
will more adequately measure emissions from all cycle phases. If such test results
demonstrate that the Supercharger System adversely affect emissions during off—cycle
conditions (defined as those conditions which are beyond the parameters of the Cold—Start
CVS—75 Federal Test Procedure), this Executive Order shall be effectively rescinded as of
the date the test results are validated. Further, if such test results or other evidence provides




                DINAN ENGINEERING—SUPERCHARGER SYSTEM—D—176—23


                                               —3.


the ARB with reason to suspect that the Supercharger System will affect the durability of the
emission control system, Dinan Engineering, Inc. shall be required to submit durability data to
show that the durability of the vehicle emission control system is not, in fact, affected and/or
that the add—on or modified part demonstrates adequate durability.

In addition to the foregoing, 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        f
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF DINAN ENGINEERING‘S
SUPERCHARGER SYSTEM.

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 /fi”’l day of January 2004.
