Changes made to the design or operating conditions of the TRD 1GR—FE Supercharger System, 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 Executive Order shall not apply to any TRD 1GR—FE Supercharger System 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 TRD 1GR—FE Supercharger System using any identification other than that shownin this Executive Order or marketing of the TRD 1GR—FE Supercharger System for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board.
