                                   State of California
                               AIR RESOURCES BOARD

                               EXECUTIVE ORDER D-620

                      Relating to Exemptions Under Section 27156
                                 of the California Vehicle Code

                                    West Coast Fiero
                             3800 lntake and Header 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-02-003;

IT IS ORDERED AND RESOLVED: That the installation of the 3800 lntake and Header
System, produced and marketed by West Coast Fiero, 13456 Beach          venue,      Marina
Del Rey, California 90292, 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 1984-1988 Pontiac Fiero
originally equipped with either the 2.5 liter 4 cylinder (1984-1988), or 2.8 liter V-6
( I 985-1988) naturally aspirated engine equipped with one of the following California
3.8 liter supercharged engines installed as part of an engine change:

The 3800 lntake and Header System consists of an open-element air intake system and
header. The 3800 lntake and Header System is required for installation of the
supercharged 3.8 liter engine.

This Executive Order is valid provided that the installation instructions for the 3800
lntake and Header 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 3800 lntake and Header
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 3800 lntake and Header 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 3800 lntake and Header System using any identification other than that
shown in this Executive Order or marketing of the 3800 lntake and Header 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
3800 lntake and Header System 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
cor~figurationusing the Cold-Start CVS-75 Federal Test Procedure (FTP), and an
examination of the On-Board Diagnostic II (OBD 11) system. A 1988 Pontiac Fiero that
had been equipped with the engine from a 1998 Buick Park Avenue (supercharged,
WGMXV03.8051, Tier-I, PC) was used for the evaluation of the 3800 lntake and
Header System. Results from emissions testing conducted at The Automobile Club of
Southern California are shown below (in grams per mile):

                       50k       NMHC        CO         NOx
                 Emission Level 0.082        1.9        0.3
                 (w. DF applied)
                       STD       0.25       3.4         0.4

                      100k       NMHC        CO         NOx
                 Emission Level 0.082        2.4        0.4
                 (w. DF applied)
                       STD       0.31       4.2         0.6

The emission test results in the modified configuration were below the applicable
certification standards. Examination of the OBD II system showed the 3800 lntake and
Header System does not affect OBD II operation. Therefore, based on the test results,
the 3800 lntake and Header System meets the criteria for exempting general criteria

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. Further, if test results or other evidence provides the
ARB with reason to suspect that the 3800 lntake and Header System will affect the
durability of emission control systems, West Coast Fiero, shall be required to submit

                      West Coast Fiero - 3800 lntake and Header - D-620

durability data to show that the durability of vehicle emission control systems are not, in
fact, affected andlor that the add-on or modified part demonstrates adequate durability:


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.

Executed at El Monte, California, this      L*       day of April 2007.
