                              EXECUTIVE ORDER D—126—47

                        Relating to Exemptions Under Section 27156
                                   of the California Vehicle Code

                                  General Motors LLC
                          LT4 E—ROD Engine Kit, Part # 19356048

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—14—012;

IT IS ORDERED AND RESOLVED: That the installation of the LT4 E—ROD Engine Kit,
manufactured and marketed by General Motors, LLC, 30003 Van Dyke Avenue,
Warren, Michigan 48090, 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 all 1995 and older passenger cars
and trucks, with up to 4500 lbs. test weight (5725 Ibs. GVWR).

The LT4 E—ROD Engine Kit is a complete supercharged engine with intercooler and
emission control package designed to change engines from 1995 and older passenger
cars and light duty trucks within the maximum weight limit (5725 lbs. GVWR). The kit is
derived from a certified 2017 Camaro LT1 engine (test group HGMXVO6.2090) but with
modifications to the original emission control module (ECM) calibration, exhaust system,
evaporative system, and air intake system. The main components of the kit with their
corresponding part numbers are listed in Attachment A. Installation of the LT1 E—ROD
Engine Kit requires complete removal of the stock pre—1996 model year engine, including
its exhaust and evaporative emission control system. The stock fuel tank, hoses and
fuel pump are retained but need to be reconfigured to meet the installation requirements
of the LT1 E—ROD Engine Kit. The kit is equipped with a fully functioning on—board
diagnostic II (OBD 1I) system except for the evaporative system checks. The stock
vehicle check engine light is retained or needs to be added for older vehicles that were
not originally equipped with a check engine light in the dashboard. Exhaust system,
catalytic converters and oxygen sensors must be installed in the location/orientation as
prescribed in the installation instructions provided with the kit. No component of this
kit has any user adjustable parameters; fuel pressure regulator, if used, must be
non—adjustable. No exhaust piping can be added between supplied exhaust
manifold and output of rear supplied converter. Each converter contains pre—
installed, welded on, upstream connecting pipes with factory flanges.

Installation of any modified or add—on parts to this engine package shall be prohibited
unless prior approval is obtained from the Air Resources Board.

This Executive Order is valid provided that the installation instructions for the LT4 E—ROD
Engine Kit will not recommend tuning the vehicle to specifications different from those of
the kit manufacturer.


                                                ig.


Changes made to the design or operating conditions of the LT4 E—ROD Engine Kit, 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 LT4 E—ROD Engine Kit using any identification other than that shown in
this Executive Order or marketing of the LT4 E—ROD Engine Kit 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 LT4 E—ROD Engine Kit shall
not be construed as an exemption to sell, offer for sale, or advertise any component of
the LT4 E—ROD Engine Kit as an individual device.

This Executive Order is granted based on emission results submitted by
General Motors LLC in certifying its naturally aspirated and supercharged 2017 model
year Chevrolet Camaro and Corvette as a new vehicle (test group HGMXVO6.2090,
LEV 3 LEV 160). The final installed engine configuration, in an applicable vehicle, is the
same as the 2017 model year Camaro or Corvette, with allowed modifications as listed in
kit description. General Motors LLC‘s new vehicle certification emissions data for the
above mentioned test group are shown below in grams per mile:

                      NMOG+NOx             Cco         HCHO

Certification            0.083             0.9         0.000

Standards                0.160            4.2          0.004

Useful Life SFTP            NMOG+NOx             Co
Emission Level
(Composite w/ df)                0.087           0.8

     Standards                   0.120 (BIN)     4.2

The certification emissions and OBD II test results submitted for new vehicle certification
have been accepted as representative of emissions in the modified configuration.
Therefore, based on the test results, the staff concludes that the General Motors LLC‘s
LT4 E—ROD Engine Kit meets the criteria for exempting general criteria parts.

The Air Resources Board 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, California Code of
Regulations, 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 THE LT4 E—ROD
ENGINE KIT.
