                                 EXECUTIVE ORDER D—425—7
                          Relating to Exemptions Under Section 27156
                                       of the Vehicle Code


                               TOYOTA RACING DEVELOPMENT
                                6.5 PSI. 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—45—9;

 IT IS ORDERED AND RESOLVED: That the installation of the 6.5 PSI. Supercharger Kit,
 manufactured and marketed by Toyota Racing Development, 1382 Valencia Ave., Tustin,
 California 92780 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 all 1992 to 1997 model—year Toyota trucks that are equipped with a 4.5L
 6 cylinder engine.

  The 6.5 PSI. Supercharger Kit includes the following main components: Eaton supercharger,
* supercharger plenum chamber, new intake air tubing, throttle—body adaptor, and all the
  necessary hardware needed for installation. Modifications to the stock engine configuration
  include the relocation of the throttle—body to the back of the supercharger, new intake air
  tubing from stock air cleaner housing to the throttle—body and from the supercharger plenum
  chamber to the stock intake manifold. The supercharger and plenum chamber are located
  on the passenger side of the engine block. No emission related components are modified
  except for a PCV hose which is relocated to the vacuum port on the throttle—body adaptor at
  the back of the supercharger. No changes are made to the stock ignition system. The kit
  includes a 3.2" diameter supercharger pulley and a 7.7" diameter crankshaft pulley.

 This. Executive Order is valid provided that the installation instructions for the supercharger
 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 supercharger, 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 does not constitute any opinion as to the effect the use of the
 supercharger may have on any warranty either expressed or implied by the vehicle
 manufacturer.


TOYOTA RACING DEVELOPMENT                                        EXECUTIVE ORDER D—425—7
6.5 PSI. SUPERCHARGER KIT                                        (Page 2 of 3)


Marketing of the supercharger using any identification other than that shown in this Executive
Order or marketing of the supercharger for an application other than those listed in this
Executive Order shall be prohibited unless prior approval is obtained from the Air Resources
Board. Exemption of the supercharger shall not be construed as exemption to sell, offer for
sale, or advertise any component of the kit as an individual device.

This Executive Order is granted based on the following submitted emissions test data on a
1995 Toyota Land Cruiser with 53,428 miles and certified to a tier 1 emission standard:

                           NMHC           CO        NOX
   120K Standards          0.46           6.4       0.98
   Device w/dfs            0.37           3.9       0.65

Test results showed that tailpipe emissions with the Supercharger Kit installed on the vehicle
met the vehicle‘s applicable emission standard during Cold Start CVS—75 Federal Test
Procedure. This Executive Order is also based on On Board Diagnostic II (OBD It) testing
conducted on the same test vehicle. Test data showed that the Supercharger Kit when
installed on the vehicle did not affect the vehicle‘s ability to perform its OBD II monitoring.

This Executive Order is granted based on submitted emissions test data which showed that
the Toyota Racing Development‘s 6.5 PSI. Supercharger Kit did not adversely affect tailpipe
emissions during the Cold Start CVS—75 Federal Test Procedure. However, the ARB finds
that reasonable grounds exist to believe that use of the Toyota Racing Development‘s
Supercharger Kit 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 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 evidence provides
the ARB with reason to suspect that the supercharger will affect the durability of the emission
control systems, Toyota Racing Development 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
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF TOYOTA RACING
DEVELOPMENT‘S SUPERCHARGER KIT.
