The GenX GM LS Cylinder Head, Series 205, 215, 220, 225, 235, 245, 255, and 260, is a set of new modified aluminum cylinder heads, designed to increase the performance of the engine by having ported and polished intake and exhaust ports, larger valve diameters, and a modified combustion chamber volume. No other changes are required for proper installation other than the remove and replacement of the cylinder head. This Executive Order is valid provided that the installation instructions for the GenX GM LS Cylinder Head, Series 205, 215, 220, 225, 235, 245, 255, and 260 will not recommend tuning the vehicle to specifications different from those of Trick Flow Specialties. Changes made to the design or operating conditions of the GenX GM LS Cylinder Head, Series 205, 215, 220, 225, 235, 245, 255, and 260, 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 Transport Research Center, Inc., East Liberty, Ohio, on a 2013 model year Camaro certified to the Low Emission Vehicle II Ultra Low Emission Vehicle (LEV II ULEV) standards and tested using the Cold Start Federal Test Procedure (FTP) and the Supplemental Federal Test Procedure (SFTP—US06) test cycle: CVS—75 FTP NMOG CO NOx HCHO Standards, Useful Life 0.070 2.1 0.04 0.011 Device Test 1 w/df ©0.044 11 0.03 0.001 Device Test 2 w/df 0.048 1.2 0.03 0.001

The GenX 255 GM LS Cylinder Head when installed on the test vehicle did not affect the vehicle‘s ability to perform its OBD II monitoring. A similar effect on vehicle emissions and OBD II monitoring is expected with the installation of the GenX GM LS Cylinder Head on the other vehicles listed in this Executive Order. 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.
