                                     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.


APPENDLX

compatible with the device, end for which exemption is requested. Specify the
correct davice model for each vahicle.                        —
