                                    State of California
                                AIR RESOURCES BOARD

                               EXECUTIVE ORDER D—601—2

                       Relating to Exemptions Under Section 27156
                                  of the California Vehicle Code

                                       Flyin‘ Miata
                              Supercharger Kit, P/N 03—900%X0

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 Supercharger Kit,
manufactured and marketed by Flyin‘ Miata, 499 35 Road, Palisade, Colorado 81526, 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 2006 to 2015 model year Mazda Miata vehicles.

The MX—5 Supercharger System consists of the following main components: Eaton MP62
supercharger with a 91.4mm diameter supercharger pulley and a 150mm crankshaft pulley,
intake manifold, bypass valve, new radiator thermostat housing, new thermostat at stock
temperature, intercooler, air intake tubing, replacement high flow fuel injectors, new air box
lid, wire extensions to the Electronic Throttle Control and MAF and IAT sensors, and a
reflashed ECM. Boost is limited to 8.0 pounds per square inch. The stock throttlebody,
fuel pump, and mass air flow sensor are all retained. Stock mass air flow sensor is
installed in the new air box lid in a stock location and orientation. The PCV breather hose
may be replaced or modified with an SAE30RY rated hose or a Mazda replacement
equivalent. All supplied fuel hoses are either Avon‘s CADbar 9000 series or a stock factory
replacement, and fuel and vapor line connectors supplied with the kit are OEM equivalent
parts. Premium only label included for inside of fuel door. Installation of the
Supercharger Kit requires the removal of the stock air filter housing and all intake air
tubing. If the stock air filter housing contains the vehicle‘s tune—up & emissions
control decal, a replacement decal must be placed in a similar location.

This Executive Order is valid provided that the installation instructions for the Supercharger
Kit will not recommend tuning the vehicle to specifications different from those of Flyin‘

Changes made to the design or operating conditions of the Supercharger 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.

This exemption is issued based on submitted emissions test data, from the SEMA Garage,
Diamond Bar, California, on a 2015 model year Mazda 2.0L Miata certified to the
LEV II ULEV emission standards and tested using the Cold—Start CVS—75 Federal Test
Procedure (FTP) test cycle, Highway Fuel Economy Test (HWFET), and the Supplemental
Federal Test Procedure (SFTP USO6/SCO03 (AC2 test + 20%)) test cycle.

Boost pressure gain was measured at 10.2 psi.

Test results showed that the Supercharger Kit when installed on the vehicle did not cause
exhaust emissions to exceed the applicable emission standards during the FTP and SFTP.
This Executive Order is also based on the On—Board Diagnostic II (OBD II) testing
conducted on the same test vehicle. The Supercharger Kit when installed on the test
vehicle did not affect the vehicle‘s ability to perform its OBD II monitoring.

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.


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.
