                               EXECUTIVE ORDER D—446—2
                       Relating to Exemptions Under Section 27156
                                     of the Vehicle Code

                                 KNIGHT ENGINEERING
                               ICEMAN COOL AIR 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 Iceman Cool Air System,
manufactured and marketed by Knight Engineering, 150 W. Mindanao Street,
Bloomington, California 92316, 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 the vehicles listed in Exhibit A.

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

This Executive Order is valid provided that the installation instructions for the Iceman
Cool Air 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 Iceman Cool Air 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 Iceman Cool Air System 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 Iceman Cool Air System using any identification other than that shown
in this Executive Order or marketing of the Iceman Cool Air System for an application

ICEMAN COOL AIR SYSTEM                                            (Page 2 of 3)

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
Iceman Cool Air 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 the vehicle 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 Knight Engineering Iceman Cool Air Systems 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 Knight Engineering Iceman Cool Air 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
Iceman Cool Air System will affect the durability of emission control systems, Knight
Engineering 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.

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.


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

 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.
