This Executive Order shall not apply to any TorqueTubes advertised, offered for sale, sold with, or installed on a new motor vehicle prior to or concurrent with transfer to an ultimate purchaser. Marketing of the TorqueTubes using any identification other than that shown in this Executive Order or marketing of the TorqueTubes for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board. This Executive Order does not constitute any opinion as to the effect the use of the TorqueTubes may have on any warranty either expressed or implied by the vehicle manufacturer. This Executive Order is granted based on SI-~bmittedemission test data generated on both 2007 model year 3.8L Jeep Wrangler and a 5.4L Ford F-150 vehicles, certified to ,the Low Emission Vehicle II Ultra Low Emission Vehicle (LEV II ULEV) emission standards and modified with the TorqueTubes. Test results showed that emission levels, with the TorqueTubes installed, met the applicable emission standards when tested using the Cold-Start CVS-75 Federal Test Procedure (FTP) test cycle for both vehicles and the Supplemental Federal Test Procedure (SFTP US06) test cycle for the Jeep Wrangler only. Examination of the OBD II system showed the TorqueTubes did not affect OBD II system operation. Results from emissions testing conducted at Quantum Technologies, Lake Forest, California, are shown below (in grams per mile with deterioration factors applied).
