State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—488—6 Relating to Exemptions Under Section 27156 of the Vehicle Code Magnuson Products, Inc. Radix Supercharger Kit 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—02—003; IT IS ORDERED AND RESOLVED: That the installation of the Radix Supercharger Kit manufactured and marketed by Magnuson Products, Inc. of 3172 Bunsen Avenue, Unit K, Ventura, CA 93003, has been found not to reduce the effectiveness of required motor vehicle pollution control devices and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for the 5.7L General Motors passenger cars listed in Exhibit A. The Radix Supercharger Kit includes the following main components: Eaton supercharger and intake manifold plenum, air intake filter and duct, air—to—water intercooler, and new fuel and ignition timing map calibrations. The stock fuel pressure regulator is retained, but the stock fuel pump is replaced with a high— capacity fuel pump. The throttle body is moved to the supercharger inlet. All other emission—related components are in the stock location relative to the throttle body. The supercharger pulley diameter is 3.5". All crankshaft pulleys are stock and maximum boost is limited to 6 psi. This Executive Order shall not apply to any Radix Supercharger Kit advertised, offered for sale, sold with, or installed on a new motor vehicle prior to or concurrent with transfer to an ultimate purchaser. This Executive Order is valid provided that the installation instructions for the Radix Supercharger Kit will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer. Changes made to the design or operating conditions of the devices, as exempted by the Air Resources Board (ARB), that adversely affect the performance of a vehicle‘s pollution control system shall invalidate this Executive Order.

Marketing of these devices using any 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 ARB. This Executive Order does not constitute any opinion as to the effect that the use of these devices may have on any warranty either expressed or implied by the vehicle manufacturer. This exemption is issued based on submitted emissions test data from an independent laboratory on a 2004 model year General Motors Corvette 206 vehicle (Test Group 4GMXVO5.7082) certified to the Low Emission Vehicle (LEV) and Supplemental Federal Test Procedure (SFTP) standards: Federal Test Procedure: NMOG CO NOx Standards (g/mi) 0.075 3.4 0.20 Device (g/mi) with df‘s applied 0.046 0.6 0.05 Additive df‘s (50k) 0.000 0.0 0.00 SFTP (USO6 Cycle): NMHC+NOX CO Standards (g/mi) 0.14 8.0 Device (g/mi) 0.08 6.4 SFTP (SCO3 Alternative AC2 Cycle): NMHC+NOX CO Standards (g/mi) 0.20 2.7 Device (g/mi) 0.03 0.1 Test results showed that the Radix Supercharger Kit when installed on the vehicle did not cause exhaust emissions to exceed the applicable emission standards during the Cold Start CVS—75 Federal Test Procedure or SFTP cycles. This Executive Order is also based on the On—Board Diagnostic !I (OBD !I) testing conducted on the same test vehicle. The Radix Supercharger Kit when installed on the test vehicle did not affect the vehicle‘s ability to perform its OBD !I monitoring. In addition, the ARB 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.
