— The open—element air filter kits include the following main components:  open—
  element air filter, throttle body adapter, crankcase breather hose, vacuum
  hose, and hose clamps.

 This Executive Order is valid provided that the installation instructions for
 the open—element air filter kits 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 open—element air
 filter kits, 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 open—element air filter kits using any identification other

 filter kits 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 open—element air filter kits 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 open—element air filter kits may have on any warranty either expressed
 or implied by the vehicle manufacturer.

 This Executive Order is granted based on a determinations that the open—
 element air filter kits will not adversely affect tailpipe emissions when
 tested under the Cold Start CVS—75 Federal Test Procedure.  No systems that
 affect the Cold Start CVS—75 or running loss emissions are bypassed in
 installing the DC Sports‘ open—element air filter kits.  However, the ARB
 finds that reasonable grounds exist to believe that use of DC Sports‘s Open—
 element air filter kits 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 open—element air filter kits adversely affect
 emissions during off—cycle conditions (defined as those

II.    CONCLUSIONS

           Based on submitted diagrams,   installation instructions,     samples,    and

examination of the applicable vehicle models, the staff concludes that DC

Sports‘ open—element air filter kits will not adversely affect exhaust

emissions from the vehicles for which the exemption is requested.

III.    RECOMMENDATION

           The staff recommends that DC Sports be granted an exemption for

their open—element air filter kits for installation on those applicable

Honda/Acura vehicles.     The staff also recommends that Executive Order D—370—2

be issued.

IV.    OPEN—ELEMENT AIR FILTER KIT DESCRIPTION

             The DC Sports open—element air filter kits have been specifically

designed for installgtion on Honda/Acura vehicles.         Each 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 installing the open—element air filter kit is to

increase its volumetric efficiency and power output at particular engine loads

and throttle openings.     At heavy engine loads and increased throttle openings,

the manifold air flow is increased by the less restrictive open—element air


filter allowing more air and fuel to enter the engine, resulting in marginally.

increased output.

            The open—element air filter used for these kit is a reusable cotton

gauze cone filter.    The filter is attached to the throttle body my means of an

adapter and hose clamps.      Vacuum hoses and crankcase breather hoses are

supplied as needed.

            The installation of the kit does not require any major modifications

to the stock Honda/Acura motor, except for the removal of the stock air filter

housing.    The stock anti—resonator chamber (for silencing the intake system)

is also bypassed.     Vacuum hoses and crankcase breather hoses that are rerouted

are accommodated by the throttle body adapter.       New parts include the open—

element air filter, throttle body adapter, vacuum hoses,      crankcase breather

hoses,   and hose clamps.

v.          BISCUSSION OF THE OPEN—ELEMENT AIR FILTER KITS

            The applicable Honda/Acura vehicles are all equipped with anti—

resonator chambers to silence air intake noise at higher engine speeds.         Some

of the anti—resonators use vacuum signals to open the anti—resonator chambers

at high engine speed.       These systems are bypassed in certain models in the

installation of the open—element air filter kits and the bypassed vacuum lines

are capped to prevent leaks.       Relocated vacuum lines and crankcase breather

hoses are connected to the throttle body adapter.       The relocated vacuum lines

and crankcase breather hoses retain the same functional requirements of vacuum

and filtered air as in the stock configuration, and are not expected to have

an effect on emissions.       The ARB did not require emission testing;   instead, an

engineering evaluation was conducted to determine the impact of the open—

element air filter kits on the emissions control systems.       The DC Sports kits

were also compared to similar air filter kits that had previously been granted

exemptions.

            In the evaluation of DC Sports‘ open—element air filter kits staff

considered such factors as the relocation of sensors and other components and

the effect of increased airflow on the emission control system.       There were no

sensors relocated or bypassed for the intake systems discussed in this

document.     The open—element air filter kits are designed to reduce the


                                          —2«—


    a1
restriction to the air entering the engine at high engine speed and load in

order to increase volumetric efficiency.       The increase in volumetric

efficiency leads to a more uniform density of intake air, allowing the engine

control module to increase the amount of fuel during combustion, leading to

increased power.    The most noticeable gains would occur at high load and

engine spsed, conditions which are not usually encountered when testing

vehicles on the CVS—75 Federal Test Procedure.       Power increases are of course

limited by the existing, unchanged, parameters of iqgnition timing, compression

ratio,   exhaust back pressure,    and normal aspiration.

           Therefore, based on the evaluation of the DC Sports systems, the

staff concludes that the installation of the open—element air filter kits will

not have an adverse effect on exhaust emissions on those applicable vehicles

when operated similar to the CVS—75 Federal Test Procedure.       However, the ARB

finds that reasonable grounds exist to believe that use of the DC Sports‘

open—element air filter kits may adversely affect emissions of motor vehicles

when operating under conditions outside the parameters of the previously

prescribed 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.

           DC Sports has submitted all the required information and fulfilled

the requirements for an exemption.
