EVALUATION OF NC SPORTS® DIRECT AIR CHARGER AND COLD AIR EXTENSION FOR AN EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS 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. Hine;
