                                 EXECUTIVE ORDER D—526

                         Relating to Exemptions Under Section 27156
                                    of the California Vehicle Code

                                  Volant Air Intake Systems
                            Volant Performance Air Intake System

  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 Volant Performance Air
  Intake System, produced and marketed by Volant Air Intake Systems, 10700 Jersey
  Blvd. Suite 670, Rancho Cucamonga, California 91730, 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 vehicles
  listed in Exhibit A.

— The Volant Performance Air Intake System includes the following main components:
  open—element reusable air filter, filter enclosure (as applicable), intake system tubing,
  crankcase ventilation hose (as applicable, which may be silicone, and a color other than
  black), assorted brackets, and hardware.

  This Executive Order is valid provided that the installation instructions for the Volant
  Performance Air Intake System 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 Volant Performance Air
  Intake System, 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 Volant Performance Air Intake System
  advertised, offered for sale, sold with, or installedon a new motor vehicle prior to or
  concurrent with transfer to an ultimate purchaser.

  Marketing of the Volant Performance Air Intake System using any identification other
  than that shown in this Executive Order or marketing of the Volant Performance Air
  Intake System 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
Volant Performance Air Intake System may have on any warranty either expressed or
implied by the vehicle manufacturer.

This Executive Order is granted based on an examination of the On—Board Diagnostic II
(OBD—I1) system of a 2002 model—year Chrysler PT Cruiser {(engine family
2CRXVO148V40, ULEV, PC) in the modified configuration, and an engineering
evaluation of the emissions impact of the device if measured using the Cold—Start CVS—
75 Federal Test Procedure. However, the ARB finds that reasonable grounds exist to
believe that use of the Volant Performance Air Intake System 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 Volant Performance Air Intake System 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
Volant Performance Air Intake System will affect the durability of emission control
systems, Volant Air Intake Systems 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.

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 VOLANT AIR
INTAKE SYSTEMS‘ VOLANT PERFORMANCE AIR INTAKE SYSTEM.

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   /57        day of October, 2001.

                                    EVALUATION SUMMARY

Manufacturer Name: Volant Air Intake Systems

Name of Device: Volant Performance Air Intake System

Background:
        Volant Air Intake Systems of 10700 Jersey Blvd. Suite 670, Rancho Cucamonga,
California 91730, has applied for an exemption from the prohibitions in Section 27156 of
the California Vehicle Code (VC) for the Volant Performance Air Intake Systems
designed for the vehicles listed in Exhibit A. The vehicle application includes those
certified to the Ultra Low Emission Vehicle (ULEV) standards.

Recommendation:             .                            .
      Grant exemption to Volant Air Intake Systems as requested and issue Executive
Order D—526.

Device Description:
        Volant Air Intake Systems‘ Volant Performance Air Intake Systems are air intake
systems specifically designed for installation on the vehicles listed in Exhibit A. The
installation of the kit does not require any major modifications to the stock motor, except
for the modification of the factory air intake system to accommodate the Volant
Performance Air Intake Systems air filter and plumbing. On some models, relocation of
the crankcease ventilation hose is required. In these cases, the Volant Performance Air
Intake Systems are supplied with crankcase ventilation hoses (which may be silicone,
and a color other than black). The filter element used in the Volant Performance Air
Intake Systems is an open—element, reusable cotton gauze unit, designed to be less
restrictive than the stock air filter.
       The Volant Performance Air Intake Systems are intended to increase the
vehicles‘ volumetric efficiency and power output at particular engine loads and throttle
openings. At heavy engine loads and increased throttle openings, the airflow into the
engine is increased because the Volant Performance Air Intake Systems are less
restrictive than stock air filters. This allows more air to enter the engine, which is
compensated by the vehicle engine control module with an increase in fuel flow,
resulting in a higher power output. However, the fuel enrichment is limited and the
typical net effect is an overall leaning effect of the fuel mixture. The leaning effect is
manifested in a marginal, but measurable, NOx increase. Worst—case vehicles are
examined for their certification emissions. In cases where certification emissions have
values low enough to accommodate any small increase in emissions (in this case NOx),
emission testing is deemed not required.

Discussion/Basis for the Recommendation:
        A 2002 Chrysler PT Cruiser with a 2.0 liter four cylinder engine (engine family
2CRXVO148V40) was used for the evaluation of the Volant Performance Air Intake
System. The test vehicle was certified to the Passenger Car Ultra Low—Emission
Vehicle (PC ULEV) standards and was equipped with an enhanced evaporative system.
Testing consisted of one CVS—75 Federal Test Procedure (FTP) in the modified
configuration (Volant Cool Air Intake installed) to set all On—Board Diagnostics (OBD) II
readiness indicators. Testing was conducted at Automotive Testing and Development
Services. No emissions measurement was required since similar systems have been
                                              1


tested previously and have shown to marginally increase the NOx when tested in
accordance with the CVS—75 FTP. This marginal increase in NOx is due to a leaning
effect of the less restrictive intake system. Since the affected vehicles have certification
values that are considerably below the standards, they can accommodate any small
increase in NOx emissions.
       Based on engineering evaluation and the OBD—II test results, the staff concludes
that the Volant Air Intake Systems‘ Volant Performance Air Intake System meets the
requirements for a VC 27156 exemption for the vehicles listed in Exhibit A.
