This exemption shall not apply to any device, apparatus, or mechanism advertised, offered for sale or sold with, or installed on, a motor vehicle prior to or concurrent with transfer to an ultimate purchaser. This Executive Order jis valid provided that installation 1nstruct1ons for this device will not recommend tuning the vehicle to specifications different from those submitted by the device manufacturer. Changes made to the design or operating conditions of the device, as exempted by the Air Resources Board, that adversely affect the performance of a vehicle‘s pollution control system shall invalidate this Executive Order . Marketing of this device using an identification other than that shown in this Executive Order or marketing of this device 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 a kit shall not be construed as an exemption to sell, offer for sale, or advertise any component of a kit as an individual device. — This Executive Order does not constitute any opinion as to the effect that the use of this device may have on any warranty either expressed or implied by the vehicle manufacturer. .

State of California AIR RESOURCES BOARD Evaluation of HKS USA, Inc.‘s Air—To—Air Intercooler System for Exemption from the Prohibitions of Yehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. June 14, 1989

Evaluation of HKS USA, Inc.‘s Air—To—Air Intercooler System for Exemption from the Prohibitions of Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue E1 Monte, CA 91731 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use).

SUMMAR Y HKS USA, Inc. (HKS)} has requested an update to their Executive Order D—186, exemption from the prohibitions of ¥ehicle Code Section 27156 for their air—to—air intercooler system for use on the OEM turbocharged vehicles listed in the appendix. Based on previous comparative test data collected in the evaluation of the exhaust emissions impact of several add—on intercooler kits and the staff‘s engineering evaluation, the staff concludes that the HKS‘s air—to—air intercooler kit will not adversely affect exhaust emissions from vehicles for which the exemption is requested. The staff recommends that HKS USA, Inc. be qgranted an exemption for their air—to—air intercooler system as requested and that Executive Order D—186—1 be issued.

Evaluation of HKS USA, Inc.‘s Air—To—Air Intercooler System for Exemption from the Prohibitions of Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. I. INTRODUCTION HKS USA, Inc. (HKS), of 20312 Gramercy Place, Torrance, California 90501, has requested an exemption from the prohibitions of Yehicle Code Section 27156 for their air—to—air intercooler system for use on the OEM turbocharged vehicles listed in the appendix. OI1I. CONCLUSIO Based on previous comparative tests evaluating the exhaust emission impact of different add—on intercooler kits and the staff‘s engineering evaluation, the staff concludes that HKS‘s air—to—air intercooler system will not adversely affect exhaust emissions from vehicles for which the exemption is requested. III. RECOMMENDATIO The staff recommends that HKS USA, Inc. be granted an exemption for their air—to—air intercooler system as requested and that Executive Order D—186—1 be issued.

IV. 0 R _SYSTEM SC N P ION The purpose of the intercooler is to increase the density of the intake air/fuel charge of a turbocharged engine by reducing the temperature of the charge air. This reduction in the intake charge temperature allows a higher charge density resulting in increased horsepower and volumetric efficiency at a given engine speed. The major components of the HKS air—to—air intercooler system are: aluminum heat exchanger, pressure pipes, cadmium plated brackets, silicone rubber connector hoses, hose clamps, compressor by—pass valve, silicone rubber vacuum and blow—by hoses. They are packaged with other installation hardware and instructions and sold as a kit. The system is designed using different design concepts, including tubing lengths, diameter and bends, to suit the requirements of the individual vehicle. The HKS air—to—air intercooler system heat exchanger is mounted in the vehicles‘ frontal air stream. The intercooler is spliced into the original intake air plumbing between the turbocharger compressor and the intake manifold throttle body. During boost conditions, compressed air, normally 230 degrees F, is cooled to 130 degrees F by the HKS intercooler core being delivered to the engine. Some RKS intercooler systems incorporate a compressor by—pass valve which routes compressor discharge directly into the compressor intake under deceleration. This arrangement prevents impeller deceleration between gear shifts and reduces shock waves in intercooler plumbing and core.

V. DISCUSSION HKS air—to—air intercooler system is similar in design as other manufacturers‘ systems that have been exempted by the Air Resources Board (ARB). Performance analyses that were previously submitted to the ARB by other manufacturers of similar system indicated that typical thermal efficiency of a turbocharger intercooler system ranges between 40% and $4%. Based on predicted efficiency of a heat exchanger on previous air temperature measurements of other exempted intercoolers installed and tested on vehicles and on a review of the device theory of operation, the staff has concluded that the use of an intercooler would not adversely affect vehicle emissions or result in the degrading of a vehicle‘s driveability. In addition, it is the staff‘s opinion that the combustion temperature will be reduced as a result of cooler intake charge with the use of the air—to—air intercooler system. This reduction in combustion temperature will reduce the formation of NOx gases in the combustion chamber, resulting in less NOx exhaust emissions . HKS air—to—air intercooler system has similar design with Spearco air—to—air intercooler system which is exempted by the ARB under E.0. D—140—3. Spearco‘s previous test results demonstrate no adverse effect on the vehicle‘s exhaust emissions of their kit.
