                            EXECUTIVE ORDER D—400
                  Relating to Exemptions Under Section 27156
                             of the Vehicle Code

                             SPIRALTECH USA, INC.
                                . SPIRALMAX


 Pursuant to the authority vested in the Air Resources Board (ARB) 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—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the Spiralmax device,
manufactured by Spiraltech USA, Inc. of 111 W. Fairview Avenue, San Gabriel,
California 91776, has been found not to reduce the effectiveness of the
applicable vehicle poliution control system, and therefore, the device is
exempt from the prohibitions of Section 27156 of the California Vehicle Code
for installation on 1996 and older model—year gasoline—powered vehicles.

_This Executive Order is valid provided that installation instructions for
the device 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 device, as exempt
by the ARB, which adversely affect the performance of a vehicle‘s pollution
control system, shall invalidate this Executive Order.

Marketing of the device using an identification other than that shown in
this Executive Order or marketing of the device for an application other
than those lTisted in this Executive Order shall be prohibited unless prior
approval is obtained from the ARB.

This Executive Order is granted based on a determination that the device
would not show an adverse effect in emissions if tested using the Cold—Start
CVS—75 Federal Test Procedure. However, the ARB finds that reasonable
grounds exist to believe that use of Spiralmax 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 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 Spiralmax adversely
 affects 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 Procedure), this Executive Order shall be effectively rescinded as of the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
 evidences provide the ARB with reasons to suspect that Spiralmax will affect
 the durability of the emission control system, Spiraltech USA, Inc. shall be
 requiréd to submit durability data to show that the durability of the

 SPIRALMAX                                        (Page 2 of 2)


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

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

 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 SPIRALTECH USA, INC.‘S SPIRALMAX.

 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 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 after the hearing that grounds for
 revocation exist.

 Executed at E1 Monte, California, this S day        April 1996.

      1.        INTRODUCTION

                Spiraltech USA, Inc. (Spiraltech) of 111 W. Fairview Avenue, San

      Gabriel, California 91776 has applied for an exemption from the prohibitions

      of Section 27156 of the California Vehicle Code for their Spiralmax device

      for installation on 1996 and older model—year gasoline—powered vehicles.

      Spiraltech has\submitted all the required information including a sample of

      the device.



      II.       CONCLUSION
uen




                Based on engineering evaluation of the operating principles of

      Spiralmax, the §taff concludes that the installation of Spiralmax will not

      have any adversely effect on exhaust emissions, if tested in accordance with

      the Cold—Start CVS—75 Federal Test Procedure, of those vehicles for which
      the exemption is requested.



      III.      RECOMMENDATION

               _Staff recommends that Spiraltech be granted an exemption as

      requested, permitting advertisement, sale and installation of Spiralmax on

      1996 and older model—year gasoline—powered vehicles, and that Executive

      Order No. D—400 be issued.


 IV.         DEVICE DESCRIPTION_AND OPERATION
             Spiralmax is a.device designed to increase turbulence in the air

 intake passage.    It is cylindrical in shape and is cut lengthwise from top

 to bottom leaving an opening which allows flexibility and varying sizes in

 diameter (See drawing in Appendix A).     One end of the cylinder is cut

 diagonally, approximately halfway down its length, into sevén (7) blades.

. The blades curve inwardly at approximately 90 degrees to the surface of the

 cylinder forming triangular spikes.     The device is constructed using 26—

 gauge stainless steel and measures 35—40 mm in height and 40—80 mm in

 diameter.

             For carbureted vehicles, the dévice is vertically installed on the

 rim of the carburetor air intake where it is secured by the air cleaner.

 For fuel—injected véhic]es, the device is inserted into the air intake hose

 between the air filter and the throttle body, downstream of the mass air.

 flow sensor, where the tension of the device secures it in place.       No

 sensors are relocated or altered by the installation of the device.



 V.          DEVICE EVALUATION AND DISCUSSION
             An engineefing evaluation was conducted to evaluate the emissions

 impact of Spiralmax.

             Spiraltech claims that the Spiralmax device, when installed on a

 vehicle‘s intake air system, swirls the intake air for a better air/fuel

 mixture.    Spiraltech stated that this, in turn, will increase engine power,

 improve fuel economy, and decrease exhaust emissions.      The ARB did not

 perform any testing on the device to substantiate the claims made by the

 manufacturer.     However, it is the staff‘s opinion that any induced

 turbulence in the intake air in a closed loop system will have no

 significant effect on exhaust emissions.       In addition, since the device is

 installed downstream of the air flow sensor, close to the intake manifold,


the device_wi]] not affect the operation of the on—board diagnostic systems.

          Based on these findings, staff has determined that Spiralmax will

not have any adverse effect on emissions.

                            Spiralmax
Description:
For EFI cars with an air—intake hose, it is simplg inserted
in the hose, closest to the manifold side. The C/ring expands
to fit, and incoming air is then swirled into the combustion
chamber .

For carburabtor or throttle body injector type cars the same
device is installed vertically, on the rim of the carburator
air intake. This will allow the incoming air to swirl as it
passes thru the carburator.                       —

The swirling effect in both cases, allows for a much better
air fuel mixture, generating more hp for the same amount of
gas. The increased hp allows the egine to generate the same
amount of power using less gas, thus obtain gas savings. The
better combustion will also lower the emissions dramatically.


Installation:
For EFI type cars with an air intake hose, remove hose clap
nearest to the manifold air intake, remove baby vacum hoses
and other clamps as necessary to lossen hose. Insert the
Spiralmax with crown facing the incoming G@irection of the air
flow, insert sufficiently to replace re—install hose to manifold.
Prior to re—installing, smooth unit to the inner circumference
of the hose, so that it is sufficiently rounded and friction
fit.

For carburator or throttle body   injectors,   open up the air filter
cover, located the carburator intake, and install unit face
up (crown facing upwards) encircling the carburator intake.
The unit may be secured by flexing the rim to fit, a metal clamp,
and or using the air cleaner cover to hold it down.
