                                            State of California

                                     EXECUTIVE ORDER D—537—2

                             Relating to Exemptions Under Section 27156
                                        of the California Vehicle Code

                                           Group—A Autosports
                                     Skunk2 Racing Intake Manifold

       Pursuant to the authority vestedin 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—45—9;

       IT IS ORDERED AND RESOLVED: That the installation of the Skunk2 Racing Intake
       Manifold, produced and marketed by Group—A Autosports, 2050 5¢" Street, Norco,
       California 92860, 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 Acura and Honda vehicles listed in Exhibit A.

       The Skunk2 Racing Intake Manifold is manufactured with a larger plenum diameter,
       larger intake runners, and smoother interior finish than those of the stock intake
       manifold in order to allow the engine to produce more power. The stock intake air
       bypass is no longer used with part number 307—05—0270.

       This Executive Order is valid provided that the installation instructions for the Skunk2
       Racing Intake Manifold 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 Skunk2 Racing Intake
       Manifold, as exempt by the Air Resources Board, which adversely affect the
       performance of the vehicle‘s pollutlon control system shall invalidate this Executive
       Order.

       This Executive Order shall not apply to any Skunk2 Racing Intake Manifold 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 Skunk2 Racing Intake Manifold using any identification other than that
       shown in this Executive Order or marketing of the Skunk2 Racing Intake Manifold for an
       application other than those listed in this Executive Order shall be prohibited unless
       prior,approval is obtained from the Air Resources Board.
Lssn


This Executive Order does not constitute any opinion as to the effect the use of the
Skunk2 Racing Intake Manifold may have on any warranty either expressed or lmphed j
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 II (OBD I1) system. A 2000 Acura Integra GSR with a 1.8
liter engine (YHNXVO1.8XA2, TLEV, PC) was used for the evaluation of the Skunk2
Racing Intake Manifold (part number 307—05—0270). Results from emissions testing
conducted at Automotive Testing and Development Services are shown below (in
grams per mile):

                       50k     t NMOG        CO         NOx       HCHO
                 Emission Level 0.081        1.637      0.085      0.0018
                 (w. DF applied)
                       STD       0.125       3.4        0.4        0.015

                      100k      NMOG         CO         NOx       HCHO
                 Emission Level 0.088        1.692      0.109      0.0021
                 (w. DF applied)
                       STD          0156    _ 4.2       0.6        0.018

The emission test results in the modified configuration were below the applicable
certification standards. Examination of the OBD II system showed the Skunk2 Racing
Intake Manifold does not affect OBD II operation. Therefore, based on the test results,
the staff concludes that the Skunk2 Racing Intake Manifold meets the criteria for
exempting general criteria parts.

However, the ARB finds that reasonable grounds exist to believe that use of the Skunk2
Racing Intake Manifold 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 Skunk2 — >
Racing Intake Manifold 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 Skunk2 Racing Intake Manifold will affect the
durability of emission control systems, Group—A Autosports 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
continues to meet the standards and procedures of Title 13, California Code of
Regulations, Section 2222, et seq.


             GROUP—A AUTOSPORTS — SKUNK2 RACING INTAKE MANIFOLD — D—537—2


     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 GROUP—A
     AUTOSPORTS‘ SKUNK2 RACING INTAKE MANIFOLD.

     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   _7¥1x       day of February, 2003.
