                            EXECUTIVE ORDER D—370—7
                     Relating to Exemptions Under Section 27156
                                  of the Vehicle Code


                                DC SPORTS
                DIRECT AIR CHARGER AND COLD AIR EXTENSION


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—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the Direct Air Charger and
Cold Air Extension, produced and marketed by DC Sports, 286 Winfield Circle, Corona,
California 92880, 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 Acura and Honda vehicles listed in Exhibit A.

The Direct Air Charger and Cold Air Extension include the following main components:
open—element reusable air filter, intake system tubing, silicone crankcease ventifation
hose (as applicable), assorted brackets, and hardware.

This Executive Order is valid provided that the installation instructions for the DC Spofis
Direct Air Charger and Cold Air Extension 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 DC Sports Direct Air
Charger and Cold Air Extension, 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 DC Sports Direct Air Charger and Cold Air
Extension advertised, offered for sale, sold with, or installed on a new motor vehicle
prior to or concurrent with transfer to an ultimate purchaser.

 DIRECT AIR CHARGER AND COLD AIR EXTENSION        (Page 2 of 3)

 Marketing of the DC Sports Direct Air Charger and Cold Air Extension using any
 identification other than that shown in this Executive Order or marketing of the DC
 Sports Direct Air Charger and Cold Air Extension 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 DC
 Sports Direct Air Charger and Cold Air Extension may have on any warranty either
 expressed or implied by the vehicle manufacturer.

  This Executive Order is granted based on an examination of the On—Board Diagnostic i1
‘_(OBD—II) system of a 2001 model—year Honda Civic (PC, ULEV) in the modified
  configuration, and an engineering evaluation of the emissions impact of the device if
  measured using the Cold—Start CVS—75 Federal Test Procedure. However, the ARB
  finds that reasonable grounds exist to believe that use of the DC Sports Direct Air
  Charger and Cold Air Extension may adversely affect emissions of motor vehicles when
  operating under conditions outside the parameters of the CVS—75 Federal 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. If such test results demonstrate that the DC Sports
  Direct Air Charger and Cold Air Extension 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 Direct Air Charger and
  Cold Air Extension will affect the durability of emission control systems, DC Sports shall
  be required to submit durability data to show that the durability of vehicle ernission
  control systems are not, in fact, affected and/or that the add—on or modified part
  demonstrates adequate durability.

  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, Cahforma Code of
  Regulatlons 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 DC SPORTS‘

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 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.

         1.   INTRODUCTION

                DC Sports, of 286 Winfield Circle, Corona, California 92880, has applied for an

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

        the DC Sports Direct Air Charger and Cold Air Extension designed for the Acura and

         Honda vehicles listed in Exhibit A.

         i. CONCLUSIONS

                    Based on engineering evaluation and an examination of the On—Board

         Diagnostic [I (OBD—II) system with the Direct Air Charger installed, the staff concludes

         that the DC Sports Direct Air Charger and Cold Air Extension 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

        ~ Direct Air Charger and Cold Air Extension for installation on the Acura and Honda

         vehicles listed in Exhibit A.

         IV. DIRECT AIR CHARGER—.AND COLD AIR EXTENSION DESCRIPTION
fas y


                    DC Sports offers various intake systems through its Direct Air Charger and

         Cold Air Extension product line. These intake systems have been specifically designed

         for installation on the vehicles listed in Exhibit A. Each system operates in conjunction

         with the original equipment manufacturer‘s (OEM) computer controlled fue] injection

         system and emission control system already certified with the stock engine, with the

         exception of the stock airbox and some intake tubing.


             The intent of installing the Direct Air Charger and Cold Air Extension is to

increase the vehicle‘s volumetric efficienéy and power output at particular engine loads

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

airflow into the ehgine is increased because the Direct Air Charger and Cold Air

Extension systems are less restrictive than stock air filters. This allows more air to enter

the enginge, which is compensated by the vehicle engine control module with an

increase in fu.el flow, resulting in a higher power output. However, the fuel enrichment is

limited and the typical net effect is an overall leaning effeét of the fuel mixture. The

leahing effect is manifested ina maArginal, but measurable, NOx increase. Worst—case

vehicles are examined for their certification emiséions. In cases where certification

emissions have values low enough to accommodate any small increase in emissions (in

this case NOx), emission testing is deemed not required.

             The Direct Air Charger locates the open elementair filter in the engine

compartment. The Cold Air Extensioh relocates the open element air filter outside of

the engine compartment adjacent to the wheel well, where the air is cooler. The reason

for the placement of the air filter to the wheel well is that the cooler air is denser and

should allowthe engine to produce more power due to the cooler air charge.

             The filter element used in the Direct Air Charger and Cold Air Extension is an

open—element, reusable cott-on gauze unit, designed to be less restrictive than the stock

air fi}ter.

    |        The installation of the kit does not require any major modifications to the

stock motor, except for the modification of the factory air intake system to accommodate

the Direct Air Charger and Cold Air Extension air filter and plumbing. On some models,

relocation of the crankcase ventilation hose is required. In these cases, the Direct Air


Charger and Cold Air Extension systems are supplied with silicone crankcase

ventilation hoses.

V.           DISCUSSION OF THE DIRECT AIR CHARGER AND COLD AIJR

EXTENSION                                             |

             No emissions measurement was réquired for the evaluation of the Direct Air

Charger and Cold Air Extension. Similar systems have been tested and have sh'own' to

have only a slight influence on emissions, namely a marginal increase in NOx due to a ‘

leaning effect of the less restrictive intake system. The affected vehicles have

certification values which are ftow enough to accommodate any small increase in NOx

emissions.

             A 2001 Honda Civic with a 1.7 liter four cylinder engine (engine family

1HNXVO1.7ZXJ9) was used for the evaiuation of the Direct Air Charger and Cold Air

Extension. The test vehicle was certified to the Passenger Car LoWQEmission Vehicle

(PC ULEV) standards and was equi}pped with an enhanced evaporative system.

Testing consisted of one CVS—75 Federal Test Procedux_'es (FTP) in the modified

| configuration (Direct Air Charger installéd) to set all On—Board Diagnostics (OBD) 11

readiness indicators. Testing was conducted at Automotive Testing and Development

Services. The ARB did not perform testing to confirm the test results submitted by the

applicant.                    |

             The Cold Air Extension was not instaliéd for testing because the engine

cooling fan used during dynamometer testing is directed toward the engine

compartment with fhe vehicle hood open. Therefore, intake air would not be cooler if

the Cold Air Extension had been installed, and there would be no difference in the effect

of the device on the operation of the OBD II system.


                  Based on engineering evaluation and the OBD—II test results, the staff

        concludes that the DC Sports Direct Air Charger and Cold Air Extension meet the

        requirements for VC 27156 exemption of.general criteria parts. However, the ARB finds

        that reasonable grounds exist to believe that use of the DC Sports Direct Air Charger

        and Cold Air Extension may adQersely affect emissions of motor vehicles when

        operating under conditions outside the parameters of the previously prescribed test

        procedure. Accordingly, thé ARB reserves the right to conduct additional test in the

        future, as such tests are devéloped.

                   DC Sports has submittéd all the required information and fulfilled the

        requirements for an exemption.
