Pursuant to the authority vested in the Air Resources Board (ARB) by Section
27156 of the Vehicle Code; and

Pursuant to the authority vested in the undersigned by Sections 39515 and.
39516 of the Health and Safety Code and Executive Order G—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the AEM Cold Air
System, part numbers 21—400 and 21—401, manufactured by Advanced Engine
Management of 15606 S. Broadway Center Street, Gardena, California 90248 has
been found not to reduce the effectiveness of the applicable vehicle
pollution control system, and therefore, the AEM Cold Air System, part
numbers 21—400 and 21—401, is exempt from the prohibitions of Section 27156
of the California Vehicle Code for installation on 1988—1991 model—year
Honda Civics (part number 21—400) and 1992—1995 model—year Honda Civics
(part number 21—401), excluding those Honda Civics that have been certified
to meet the California Transitional Low Emission Vehicle emission standards
(0.125 grams/mile NMOG).

This Executive Order is valid provided that installation instructions for
the device will not recommend tuning the vehicle to specifications different
from those submitted by the manufacturer.                           —

Changes made to the design or operating conditions of the device,       as exempt
by the ARB, which adversely affect the performance of a vehicle‘s pollution
control system shall invalidate this Executive Order.

Marketing of the device using an identification other than that shown in
this Executive Order or marketing of the device for an application other
than those listed in this Executive Order shall be prohibited unless prior
approval is obtained from the ARB.    Exemption of the device shall not be

of the kit as an individual device.

This Executive Order is granted based on the determination that the device
would not show an adverse effect in emissions if tested using the Cold—Start
CVS—75 Federal Test Procedure. However, the ARB finds that reasonable
grounds exist to believe that use of the device 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 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 device 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 device will affect
the durability of the emission control system, Advanced Engine Management
shall be required to submit durability data to show that the durability of
the vehicle emisston 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.

T.            INTRODUCTION
|             Advanced Engine Management (AEM) of 15606 S. Broadway Center

    Street, Gardena, California 90248 has applied for an exemption from the

    prohibitions of Section 27156 of the California Vehicle Code for their AEM

    Cold Air System, part numbers 21—400 and 21—401, for installation on 1988—

    1991 model—year Honda Civics and 1992—1995 model—year Honda Civics,

    respectively, excluding those Honda Civics that have been certified to meet

    the CaTifornia Transitional Low Emission Vehicle emission standards (0.125

    grams/mile NMOG).   AEM has submitted all the drawings, specifications, and

    the installation instructions for the AEM Cold Air System for evaluation.



    II.       CONCLUSION

              Based on an engineering evaluation, the staff concliudes that the

    AEM Cold Air System, part numbers 21—400 and 21—401, will not advetsely

    affect the exhaust emissions from those vehicles for which the exemption is

    requested, and therefore, meets the criteria set forth in Section 27156 of

    the California Vehicle Code and Title 13 of the California Code of
    Regulations.



    III.      RECOMMENDATION

              The staff recommends that AEM be granted an exemption as requested

    for their AEM Cold Air System, part numbers 21—400 and 21—401, and that

    Executive Order No. D—392 be issued.


 IV.         DEVICE DESCRIPTION AND OPERATION
             The AEM Cold Air System, partvnumbers 21—400 and 21—401, is

 designed to replace the original equipment manufacturer (OEM) intake air

 system including the intake air pipe, resonator, air cleaner, and the intake

 air duct.    The AEM Cold Air System, part number 21—400, has been designed

 for insta]]ation'on 1988—1991 model—year Honda Civics, and part number 21—

 401 has been designed for installation on 1992—1995 model—year Honda Civics.

hThe two systems are identical in their components with the exception of the

 air pipes — part number 21—400 consists of two connecting air pipes whereas

 part number 21—401 consists of only one air pipe.

             The AEM Cold Air System utilizes an air filter, Turbo—Flow Air

 Funnel, inlet air pipe(s), and the necessary connection hoses and clamps.

The air f11ter is a conical frustum with woven cotton fabric sandwiched

between two layers of wire mesh screen.     The filter diameters range from 5

to 7 inches, and the height measures 6 inches. ‘ The base of the air filter

is attached to the Turbo—Flow Air Funnel measuring 7 inches in diameter and

connects to the 2.5 inches diameter Turbo—Flow Air Horn.     The air pipes are

constructed of aluminum for its high resistant to corrosion and its light

weight.   The two connecting air pipes for part number 21—400 measure 23.07

inches and 11.30 inches in\center1ine lengths, 2.5 inches in outer diameter,

and 0.065 inches in wall thickness.     The air pipe for part number 21—401

measures 35.03 inches in centerline length, 2.5 inches in outer diameter,

and 0.065 inches in wall thickness.     The outlet of the air pipe is fitted to
the throttle body using a connector and a clamp.

             The AEM Cold Air System operates in conjunction with the OEM

computer—controlled fuel injection and emission control systems.     The

installation of the AEM Cold Air System does not re—route, modify, remove,

or interfere with the required emission control system components.     The


tunae—up specifications are also unaltered from the OEM tune—up parameters.



V.           DEVICE EVALUATION AND DISCUSSION
             The AEM Cold Air System has been designed for application on 1988—

1995 model—year Honda Civics.     An engineering evaluation was conducted to

determine the imfiact of the AEM Cold Air System on exhaust emissions.        The

major concerns regarding the cold air system are that the system may

significantly alter the afr flow resulting in an increase in evaporative

and/or exhaust emissions and the system modifies the existin§ intake air

duct which hay affect exhaust emissions.

             Since the AEM Cold Air System replaces a closed air cleaner
housing with an open element air cleaner, gasoline vapors could escape into

the atmosphere.     The vehicles for which the exemption is requested are

equipped with electronic fuel injection systems which by design eliminate

potential leaks.     The fuel injection valves are electromagnetically actuated

where during static conditions, the fuel injectors are designed to be closed

tightly.    The electromagnet pulls the injector open against the fuel flow

making it more difficult to open with increased fuel flow and pressure.           In

addition, fuel injected systems utilize intake manifolds which are designed

to allow air f1pw in only one direction, inward to the intake valve.        The

installation of the AEM Cold Air System doesvnot alter the location of the

evaporative emissions canister or hoses;     Wifh these findings, staff

concludes that use of the open element air cleaner will not have an adverse

effect on evaporative emissions.

           _ The vehicles for which the exemption is requested use speed

density fuel injection systems where intake manifold pressure and engine

speed are used to calculate the air flow volume.     Based on the calculated

air flow, the engine control module (ECM) determines the required amount of


fuel for achieving the proper air—fuel ratio under various vehicle operating

conditions.   Since the AEM Cold Air System inlet is placed low and outside

of the aengine compartment, it may draw in colder and denser air.    In order

to maintain the proper air—fuel ratio, the ECM compensates for this change

in air density through a signal from the intake air temperature sensor which

is located in thé intake manifold.   The installation of the AEM Cold Air
System does not alter the location of the intake air temperature sensor.

Therefore, the change in the air induction system will not affect the air—

fuel ratio, and in turn, the exhaust emissions.

          Since the primary purpose of the air cleaner duct is to reduce

intake tract noise on fuel injected vehicles, the replacement of the OEM air

duct and the resonator with the AEM Cold Air System will not adversely

affect exhaust emissions.
          Based on the above evaluation, staff concludes that the AEM Cold

Air System will have no adverse effect on exhaust emissions during closed—

loop operations, which are characterized by the Cold—Start CVS—75 Federal

Test Procedure.   However, during open—loop conditions, such as quick

accelerations, stoichiometric air—fuel ratio is not maintained, and the

exhaust emissions could potentially increase.     Since there is no established

test procedure to evaluate emissions during open—loop driving conditions,

the ARB has not required or conducted any testing.    The ARB reserves the

right to conduct emission tests, in the future, as such tests are developed,

that will more adequately measure emissiofis from all driving cycles.

          Advanced Engine Management has submitted all the required

information and has fulfilled the requirements for an exemption.
