HIPERFLOW INDUCTION SYSTEM                        (Page 2 of 2)


This Executive Order is granted based on an evaluation if emissions tests
were conducted in accordance with Cold—Start CVS—75 Federal Test Procedure.
However, the Air Resources Board finds that reasonable grounds exist to
believe that use of the Hiperflow Induction system may adversely affect
emissions of motor vehicles when operating under conditions outside the
parameters of the previously prescribed test procedures. Accordingly, the
Air Resources Board 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 Hiperflow Induction system 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Order shall be effectively rescinded as of the date the test results are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 Air
Resources Board with reason to suspect that the Hiperflow Induction system
will affect the durability of the emission control, Automotive Systems
Group, Inc. shall be required to submit durability data to show that the
durability of the vehicle emissions 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 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 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 AUTOMOTIVE SYSTEMS GROUP, INC.‘S HIPERFLOW INDUCTION 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 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 after hearing
that grounds for revocation exist.

Executed at El Monte, California, this zszay       f April, 1996.

                         CALIFORNIA CODE OF REGULATIONS



I.        INTRODUCTION

         Automotive Systems Group, Inc.    (ASG) of 6644 San Fernando Road,

Glendale, CA, 91201 has applied for an exemption from the prohibitions in

Section 27156 of the California Vehicle Code for the Hiperflow Induction system

designed for installation on the following vehicles:


Part Number .          Model Years   Vehicle Models                     Displacement

H03041                 1988—1991     Honda Civic CRX                    1. 6L
H03042                 1992—1995     Honda Civic DX, EX, LX, Si         1. 6L

H03045                 1994—1995     Acura Integra RS and LS®            1. 8L.
H03046                 1994—1995     Acura Integra GSR                   1. 6L

       Automotive Systems Group, Inc. submitted installation instructions with

drawings and description of the kit.       Automotive Systems Group,    Inc. has

submitted a sample Hiperflow Induction system which was evaluated for this

application.




II.      CONCLUSTONS

       Based on an engineering evaluation of the Hiperflow Induction system, the

staff concludes that Automotive Systems Group,         Inc.‘s Hiperflow Induction

system will not adversely affect exhaust emissions from the vehicles for which

the exemption is requested.




III.   RECOMMENDATION

       The staff recommends that ASG be granted an exemption for their Hiperflow

Induction system for installation on the vehicles listed above.          The staff also

recommends that Executive Order D—377—3 be issued.


IV.   HIPERFLOW INDYCTION SYSTEM DESCRIPTION AND OPERATION

      The Hiperflow Induction system consists of an open element air filter and

intake pipe with all the necessary mounting brackets, bolts, screws, and nuts

for installation.   According to ASG,   the Hiperflow Induction system is designed

to be less restrictive than the OEM air filter system to allow the engine to

gain more horsepower.   The Hiperflow Induction séZ;em does not require any

significant relocation or modification of any of the OEM emission control

components.

      The Hiperflow Induction system uses a K & N filter made of woven fabric

sandwiched between two layers of wire mesh screen and a velocity stack which

serves to smooth the incoming air flow.     The Hiperflow Induction system does

not defeat any emission control devices required— by the manufacturer nor does

it alter or circumvent the vehicle‘s on—board diagnostic system.

      All of the Honda Civic and Acura Integra models in this application have a

positive crankease ventilation (PCV) breather hose attached to the original

equipment manufactuer‘s (OEM‘s)   intake tract.   ASG provides a por£ for the PCV

breather hose and an extension for this hose since the intake tract requires

this hose to be moved slightly upstream from the OEM configuration.

      The Automotive Systems Group, Inc. Hiperflow Induction system does not

affect the tune—up specifications.


v.   DISCUSSION

     The ASG Hiperflow Induction system is designed for installation on the

vehicles listed below:


Part Number       Model Years     Vehicle Models                       Displacement

H03041            1988—1991       Honda   Civic CRX                    1. 6L
H03042            1992—1995       Honda   Civic DX, EX, LX, Si         1. 6L
H03042            1992—1995       Honda   Civic del Sol S and Si       1. 6L
H03045            1994—1995       Acura   Integra RS and LS            1.8L
H03046            1994—1995       Acura   Integra GSR                  1. 6L

     An engineering evaluation was conducted to determine the impact of the

Hiperflow Induction system on emissions.        The Air Resources Board‘s (ARB‘s)

concerns regaiding the air filter are that the air flow could significantly

increase evaporative emissions,   changes in the mass air flow measurement could

affect exhaust emissions, and the positive crankcase ventilation (PCV)         system

may be compromised by an open element air filter.




     Since the ASG Hiperflow Induction system replaces a closed air cleaner

housing with an open element filter, the ARB was concerned that gasoline vapors

could escape from the manifold, through the open element filter, into the

atmosphere.    The vehicles for which exemption is requested are equipped with

electronic fuel injection, which is designed to eliminate potential gasoline

vapor leaks.    During static condition, the fuel injectors are designed to

operaté by an electromagnet that pulls the injector open against the fuel flow.

The ARB has previously reviewed tests conducted on various fuel injector sizes

in which fuel flow and pressure were simultaneously increased.        The tests

                                          —3—


showed that as pressure is increased, the fuel injectors tend to hydraulically

lock.     This condition causes the injector to be more difficult to open and

reduces leaks.     In addition, fuel injected vehicles use intake manifolds which

are designed to flow air in only one direction,     inward to the intake valve.

Furthermore, the design of the Hiperflfiw Induction system does not alter the

location of the evaporative emissions components or hoses.      With these

findings, staff concludes there will be no adverse impact on evaporative

emissions due to the use of an open element air cleaner.

        ASG stated that the mass air flow measurement technique used on the

vehicles for which the exemption is requested are the manifold absolute

pressure sensor for speed—density calculations.      The open element air filter

does not have a housing or intake ducting which straighten the intake flow to

allow for laminar flow.     This could cause the intake flow to be turbulent.     ASG

states that the Hiperflow Induction system does not require alteration or

modification of the OEM specifications.      The manifold absolute pressure sensors

on‘the vehicles listed above are located downstream from tfie air filter element

and thus, the pressure sensing and subsequent fuel metering capabilities will

not be adversely affected by the Hiperflow Induction system.      In addition,

pressure sensing capabilities should not be significantly affected by changes

in flow conditions caused by an open element air filter.

        All of the Honda Civic and Acura Integra models in this application have a

positive crankcase ventilation (PCV) hose attached to the original equipment

manufacturer‘s (OEM‘s)    intake tract.   ASG provides a port for the PCV breather

hose and an extension for this hose since the intake tract requires this hose

to be moved slightly upstream from the OEM configuration.      Thus the placement

of this hose on the Hiperflow Induction system filter should not affect the

operation of the system.    Additionally, the PCV breather hose is used to


supply fresh air to the crankcase through a one—way checkvalve which does not

allow the passage of vapors in the air cleaner direction. Therefore, no

emissions impact is expected from this connection.

     The vehicles for which the exemption is requested are designed to operate

in a closed—loop configuration, which is characterized by the Cold—Start CVS—75

Federal Test Procedure driving cycle.      While.the vehicle operates under closed—

loop configuration, the on—board computer monitors the air/fuel mixture to

maintain it near a stoichiometric condition,.      The on—board computer receives

voltage signals frcm‘the oxygen sensor and interprets them as either richer or

leaner than a stoichiometric fuel mixture.       Based on the oxygen sensor signal,

the on—board computer either ificreases the amount of air flow (to léan the

mixture) or increases the amount of fuel      (to richen the mixture) to maintain

the fuel mixture near stoichiometric.       Although the Hiperflow Induction system

could change the air flow, the on—board computer will compensate and keep fhe

air/fuel mixture at stoichiometric levels during closed—loop operations.

Therefore, the Hiperflow Induction system will have no adverse affects on

exhaust emissions of the affected vehicles during closed—loop operations.

     However, during open—loop operations such as quick accelerations, air and

fuel is being supplied on demand and the fuel mixture is not necessarily

maintained near stoichiometric.       Although the Hiperflow Induction system could

potentially increase emissions during open—loop operations, the ARB has not

established an official test procedure to evaluate emissions during open—loop

operations.   The ARB,   therefore,   reserves the right to conduct emissions tests,

in the future, as such tests are developed, that will more adequately measure

emissions from all driving cycles.
