                                   EXECUTIVE ORDER D—126—4

                            Relating to Exemptions Under Section 27156
                                       of the California Vehicle Code

                              General Motors Service Parts Operations
                                  GMSPO 2.4 L Supercharger Kit

       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 GMSPO 2.4 L.
     Supercharger Kit (p/n 12498287), marketed by General Motors Service Parts
     Operations, and produced by Roush Industries, 28400 Plymouth Rd., Livonia, Michigan
     48150, 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 2000—2002 GM 2.4 liter Cavalier & Sunfire vehicles
     with manual transmission.

     The GMSPO 2.4 L Supercharger Kit (p/n 12498287) consists of a new intake manifold
     assembly that contains a Magnuson supercharger assembly, an intake manifold, a set
     of 3.7 gram/sec fuel injectors to replace the stock injectors (3.3 gram/sec), replacement
     manifold absolute pressure sensor, and a new fuel calibration that is downloaded onto
     the stock ECU. The GMSPO Supercharger Kit utilizes a 2.800 inch diameter pulley, the
     stock crankshaft pulley is retained.

     This Executive Order is valid provided that the installation instructions for the GMSPO
     2.4 L Supercharger Kit will not recommend tuning the vehicle to specifications different
     from those submitted by the device manufacturer.                                  '

     Changes made to the design or operating conditions of the GMSPO 2.4 L Supercharger
     Kit, as exempt by the Air Resources Board, which adversely affect the performance of
     the vehicle‘s pollution control system shall invalidate this Executive Order.

    This Executive Order shall not apply to any GMSPO 2.4 L Supercharger Kit advertised,
    offered for sale, sold with, or installed on a new motor vehicle prior to or concurrent with
    transfer to an ultimate purchaser.

    Marketing of the GMSPO 2.4 L Supercharger Kit using any identification other than that
    shown in this Executive Order or marketing of the GMSPO 2.4 L Supercharger Kit 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
 GMSPO 2.4 L Supercharger Kit may have on any warranty either expressed or implied
 by the vehicle manufacturer.

 This Executive Order is granted based on emission test results in the modified
 configuration using the Cold—Start CVS—75 Federal Test Procedure and an examination
 of the On—Board Diagnostic !I (OBD !1) system. A 2002 GM Sunfire with a 2.4 liter
 engine (2GMXVO2.4022, LEV, PC) was used for the evaluation of the GMSPO 2.4 L
 Supercharger Kit. Results from emissions testing conducted at Roush Industries
 Vehicle Emissions Laboratory, of Livonia, Michigan, are shown below (in grams per
 mile):

                       50k       NMOG        CO         NOx       HCHO
                 Emission Level 0.067        1120       0.163      0.001
                 (w. DF applied)
                       STD       0.075       3.4        0.2        0.015

                      100k         NMOG      CO        NOx        HCHO
                 Emission Leve!    0.068     1.240      0.183      0.001
                 {(w. DF applied)
                        STD       0.090      4.2        0.3        0.018

The emission test results in the modified configuration were below the applicable
certification standards. Examination of the OBD II system showed the GMSPO 2.4 L
Supercharger Kit does not affect OBD I! operation. Therefore, based on the test results,
the staff concludes that the GMSPO 2.4 L Supercharger Kit meets the criteria for
exempting general criteria parts.

However, the ARB finds that reasonable grounds exist to believe that use of the
GMSPO 2.4 L Supercharger Kit may adversely affect emissions of motor vehicles when
operating under conditions outside the parameters of the CVS—75 Federal Test
Procedure. 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 GMSPO 2.4 L.
Supercharger Kit 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 the
ARB with reason to suspect that the GMSPO 2.4 L Supercharger Kit will affect the
durability of emission control systems, General Motors Service Parts Operations shall
be required to submit durability data to show that the durability of vehicle emission
control systems are not, in fact, affected and/or that the add—on or modified part
demonstrates adequate durability.

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

GENERAL MOTORS SERVICE PARTS OPERATIONS — GMSPO 2.4 L SUPERCHARGER KIT — D—126—4


 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 GMSPO 24L
 SUPERCHARGER KIT.

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   __/Z*      day of June, 2002.

GENERAL MOTORS SERVICE PARTS OPERATIONS — GMSPO 2.4 L SUPERCHARGER KIT — D—126—4


                                  EVALUATION SUMMARY

   Manufacturer Name: General Motors Service Parts Operations

   Name of Device: GMSPO 2.4 L Supercharger Kit

   Background:
         Roush Industries of 28400 Plymouth Rd., Livonia, Michigan 48150, on behalf of
  General Motors Service Parts Operations, has applied for an exemption from the
  prohibitions in Section 27156 of the California Vehicle Code (VC) for the GMSPO 2.4 L
  Supercharger Kit designed for the 2000—2002 GM 2.4 liter Cavalier & Sunfire vehicles
  with manual transmission.

«_ Recommendation:
         Grant exemption to General Motors Service Parts Operations as requested, and
  issue Executive Order D—126—4.

  Device Description:
              The intent of installing the GMSPO 2.4 L Supercharger Kit is to increase
  power output from the engine. The power increase is due to the increase in air
  induction by pressurization by the supercharger, which is accompanied by fuel
  enrichment by the upgraded fuel injectors and fuel calibration.
              The GMSPO 2.4 L Supercharger Kit was designed to be instalied on 2000—
  2002 GM 2.4 liter Cavalier & Sunfire vehicles with manual transmission. The GMSPO
  Supercharger Kit (p/n 12498287) includes a new intake manifold assembly that contains
  a Magnuson supercharger assembly, an intake manifold, a set of 3.7 gram/sec fuel
  injectors to replace the stock injectors (3.3 gram/sec), replacement manifold absolute
  pressure sensor, and a new fuel calibration that is downloaded onto the stock ECU.
  The GMSPO Supercharger Kit utilizes a 2.800 inch diameter pulley, and the stock
  crankshaft pulley is retained. Maximum boost produced by the supercharger is 5.14
  PSI.

  Discussion/Basis for the Recommendation:
             A 2002 GM Sunfire with a 2.4 liter engine (2GMXVO2.4022) was used for the
  evaluation of the GMSPO 2.4 L Supercharger Kit. The test vehicle was certified to the
  passenger car Low—Emission Vehicle emission standards and was equipped with On—
  Board Diagnostic (OBD) II system. Testing consisted of one CVS—75 FTP in the
  modified configuration to set all readiness codes, and measure emissions. The ARB did
  not perform testing to confirm the test results submitted by the applicant.
         Results from emissions testing conducted at Roush Industries Vehicle Emissions
  Laboratory, of Livonia, Michigan, are shown below (in grams per mile):


                            50k       NMOG       CO        NOx        HCHO
                     Emission Level 0.067        1.120     0.163       0.001
                     {(w. DF applied)
                            STD       0.075      34         0.2        0.015

                          100k       NMOG        CO        NOx        HCHO
                     Emission Level 0.068        1.240     0.183       0.001
                     (w. DF applied)
                           STD       ©.090      4.2        0.3         0.018

            The emission test results in the modified configuration were below the applicable
    certification standards. All OBD II system readiness indicators set in the modified
    configuration, and no diagnostic trouble codes were triggered. Therefore, based on the
~s. test results, the staff concludes that the GMSPO 2.4 L Supercharger Kit meets the
    criteria for the exemption of general criteria parts. However, the ARB finds that
    reasonable grounds exist to believe that use of the GMSPO 2.4 L Supercharger Kit may
    adversely affect emissions of motor vehicles when operating under conditions outside
    the parameters of the previously prescribed test procedure. Accordingly, the ARB
    reserves the right to conduct additional emission tests in the future, as such tests are
    developed.
           Based on the CVS—75 FTP and OBD—II test results, the staff concludes that the
    GMSPO 2.4 L Supercharger Kit meets the requirements for a VC 27156 exemption for
    the 2000—2002 GM 2.4 liter Cavalier & Sunfire vehicles with manual transmission.
