The High Flow Cold Air Intake System includes the following main components:
Custom K&N filter, filter to air flow meter pipe, insulating filter mounting
bracket,   and hardware kit.

This Executive Order is valid provided that the installation instructions for
the air filter kit 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 air filter kit, as
exempt by the Air Resources Board,       which adversely affect the performance of
the vehicle‘s pollution control system shall invalidate this Executive Order.

Marketing of the air filter kit using any identification other than that shown
in this Executive Order or marketing of the air filter kit for an application
other than those listed in this Executive Order shall be prohibited unless
prior approval is obtained from the Air Resources Board.  Exemption of the air
filter kit shall not be construed as exemption to sell,       offer for sale,    or
advertise any component of the kit as an individual device.

This Executive Order does not constitute any opinion as to the effect the use
of the air filter kit may have on any warranty either expressed or implied by
the vehicle manufacturer.

This Executive Order is granted based on an engineering evaluation based on
the Cold—Start CVS—75 Federal Test Procedure.  However, the ARB finds that
reasonable grounds exist to believe that use of the High Flow Cold Air Intake
System 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 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 High Flow Cold 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        Test Procedure), this Executive Order shall be effectively rescinded as of the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 High Flow Cold Air
        Intake System will affect the durability of the emission control system, Dinan
        shall be required to submit durability data to show that the durability of the
        vehicle emission 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.

I.      INTRODUCTION

             Dinan Engineering,    Inc.   of 150 South Whisman Road,     Building E,

Mountain View,     California 94041 has applied for an exemption from the

prohibitions in Section 27156 of the California Vehicle Code (VC) for their

air filter kit designed for 1992—97 3—Series BMW vehicles.

II.     COoNCLUSIONS

             Based on an engineering evaluation, the staff concludes that Dinan

Engineering,    Inc.‘s High Flow Cold Air Intake System will not adversely affect

exhaust and evaporative emissions from the vehicles for which the exemption is

requested.

III.      RECOMMENDATION

             The staff recommends that Dinan Engineering,        Inc. be granted an

exemption for their High Flow Cold Air Intake System for installation on those

applicable BMW vehicles.        The staff also recommendsvthat Executive Order

D—176—11 be issued.

IV.     HIGH FLOW COLD AIR    INTAKE   SYSTEM DESCRIPTION

            The High Flow Cold Air Intake System has been specifically designed

for installation on 1992—97 3—Series BMW vehicles.            The kit operates in

conjunction with the original equipment manufacturer‘s           (OEM)   computer

controlled fuel injection system and emission control system already certified

with the stock engine.

            The purpose of modifying the stock intake air filter is to increase

air flow to the engine‘s combustion chamber by installing an oversized open

element K&N air filter.        The new air filter is placed at the location of the

vehicle‘s horn.        Dinan Engineering,   Inc. claims this will bring air into the

combustion chamber that is slightly cooler since this location does not draw

air from the engine or radiator.‘         The installation of this kit does not

require the relocation of any vacuum hoses or sensors,           including the mass air

flow sensor.     The 1992—95 BMWs have a throttle pre—heat thermostat which is

part of the vehicle‘s radiator system.          This thermostat is attached to the

stock air box and is transferred to the new air filter kit.              It is located on

the tubing between the mass air flow sensor and filter.


v.        DISCUSSION OF THE HIGH FLOW COLD AIR INTAKE SYSTEM

           An engineering evaluation was conducted to determine the impact of

the air filter kit on the vehicle‘s emissions.          The Air

Resources Board‘s (ARB‘s) concerns regarding the air filter kit is the

potential to increase evaporative and exhaust emissions and its compatibility

with the On Board Diagnostic II      (OBD II) system.

          To understand what effect the air filter kit may have on the

vehicle‘s evaporative system,      staff compared the stock and the new aftermarket

configurations.       In the stock configuration, the air filter box is connected

to the mass air flow sensor by hardened rubber tubing, vacuum lines and

miscellaneous sensors are located after the mass air flow sensor.            Dinan

Engineering,   Inc.   designed their air filter kit similar to stock,       except that

the tube connecting the mass air flow sensor to the open element air filter is

longer in length.      The mass air flow sensor and its components are not moved

or modified.      BMW produced some 1996 and 1997 3—Series vehicles certified to

an Enhanced Evaporative Emission standard.       Staff believes that the air filter

kit would not have an emissions impact ofi these vehicles since none of the

evaporative lines are cut, moved or modified.       The air filter box is not

considered part of BMW‘s evaporative emissions control system.            Therefore,   no

change in the vehicle‘s evaporative emissions is expected from the use of the

copen element air filter.

          The vehicles which the exemption is requested are designed to

operate in a closed—loop confiqguration,    which is characterized by the Cold—

Start CVS—75 Federal Test Procedure driving cycle.         When a vehicle operates

under closed—loop configuration, the on—board computer monitors the air/fuel

mixture to maintain it near stoichiometric conditions.            The on—board computer

receives voltage signals from the oxygen sensor and interprets them either to

increase the amount of air flow (to lean the mixture) or increase the amount

of fuel flow   (to richen the mixture).    Although the Dinan Engineering,       Inc.‘s

High Flow Cold Air Intake System could change the air flow,          the on—board

computer will compensate and keep the air/fuel mixture at stoichiometric

levels during closed—loop operations.      Therefore, the Dinan Engineering,

Inc.‘s High Flow Cold Air Intake System will have no adverse effects on

exhaust emissions of the affected vehicles during closed—loop operations.
                                          —2~


         Staff evaluated the effect of the air filter kit on the vehicle‘s

OBD II system by conducting an OBD II monitor check on a 1997 BMW M3.      The OBD

II check was conducted at the ARB‘s Haagen—Smit Laboratory.     The scan tool

indicated that the readiness/function code is set and no diagnostic trouble

code is stored.   If the readiness/function code is not set, then a full

diagnostic check of the monitored components and systems have not been

completed, and staff would have to determine if the air filter kit was at

fault.

         Dinan Engineering,   Inc.   has submitted all the required information

and fulfilled the requirements for an exemption.
