                      Relating to Exemptions Under Section 27156
                               of the California Vehicle Code

                               Toyota Racing Development
                                Scion tC 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 Scion tC Supercharger
Kit, manufactured and marketed by Toyota Racing Development, 19001 South Western
Avenue, Torrance, California, 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 2005 through 2007 model year
Scion tC vehicles equipped with a 2.4 liter engine.

The Scion tC Supercharger Kit includes the following main parts: a Vortech V5F
supercharger with a maximum boost of 7 pounds per square inch, a 2.8 inch diameter
supercharger pulley and a stock crankshaft pulley, a by-pass valve, four replacement
fuel injectors rated at 400 cubic centimeters per minute, an air filter lower housing and
element, a replacement Toyota V6 hydrocarbon adsorber cartridge that is permanently
attached to the stock air cleaner lid, an air inlet trumpet diffuser, an air intake tubing, a
160 degree F thermostat, and a reprogrammed OEM ECU. The stock mass airflow
sensor and air cleaner lid (airbox top) are retained. The stock hydrocarbon adsorber in
,the air cleaner lid is removed and replaced with the Toyota V6 hydrocarbon adsorber
cartridge.

This Executive Order is valid provided that the installation instructions for the Scion tC
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 Scion tC 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 Scion tC 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 Scion tC Supercharger Kit using any identification other than that shown
in this Executive Order or marketing of the Scion tC 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 Scion
tC 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, Supplemental Federal
Test Procedure (US061SC03), and an examination of the On-Board Diagnostic II (OBD II)
system. A 2007 model year Scion tC with a 2.4 liter engine (7TYXV02.4BEA,
LEV II ULEV, PC) was used for the evaluation of the Scion tC Supercharger Kit. Results
from emissions testing conducted at Quantum Technologies, Lake Forest, California, are
shown below (in grams per mile with deterioration factors applied):

The emission test results in the modified configuration were all below the applicable
certification standards. Examination of the OBD II system showed the Scion tC
Supercharger Kit does not affect OBD II system operation.

The Air Resources Board 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 CONS-TITUTEA 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 SCION TC
SUPERCHARGER KIT.
